Rikyu asks Mitsunari if she did well during the call, to which Mitsunari says that mentioning Hideyori's name would force Chacha to react. This, in addition to having Yamanami appear on the call, is all just part of baiting Chaldea into the Singularity, as it would be difficult for them to just trust Rikyu. Thankfully for them, Yamanami is real good at selling out his friends. Yamanami just wonders if Akesato is safe and sound, and Mitsunari says that a hostage is useless if dead. As long as Yamanami follows orders, her life is guaranteed. Mitsunari turns to Rikyu, making sure she understands the same applies to her, and then leaves the room.
Rikyu sighs at how Mitsunari is just as good at annoying people as he was in life. Yamanami asks why Rikyu serves Mitsunari. Rikyu, being a merchant, merely sides with the one who has the upper hand. She couldn't see herself selling out everyone else just for the sake of a single girl, like Yamanami. The profits wouldn't be balanced at all. Yamanami seems to understand it's Rikyu's doing that Akesato is held hostage to begin with, and Rikyu confirms that she was the one who found the girl wandering around here and handed her over to Mitsunari. It seems that this place, this Singularity, gathers souls that have unfinished business in life. As such, Akesato was most likely here looking for Yamanami. Much the same applies to Yamanami himself, to Mitsunari, and to Rikyu. They are ones who clinged to their lingering attachments from life; the losers of history. It is, for all intents and purposes, a landfill.
Rikyu leaves to see to it that Chaldea doesn't die from lack of tea. Outside, it seems that someone had been eavesdropping. The scene cuts to dark and we see the sprite of the girl from before. She doesn't say anything, but she seems to have appeared in Gudao's dream. And without uttering any words, tears stream down her face. Gudao wakes up again, having apparently passed out due to lack of tea, and now having being given some more. You ask about the girl in the dream, but Nobu just says this isn't exactly the time to be dreaming about girls. Majin is still out cold, in a state that appears much like death, except since she's a Servant she would've disappeared if she was really dead. Iyo can't seem to sense any magical energy reaction from her either. She does, however, recognize that the large scar across the body is from Kukochihiko's sword of the beast. It's a sword originating from the beast god, a cursed tool from Kunakoku that sets the curse of the beast upon men. It causes them to lose their reasoning and turn into beasts. Nobu can't deal with this, imagine having someone named "[Alter Ego] Okita Souji Alter (doggie)"! Either way, since the sword is veiled in Mystery from the Age of Gods, not even Iyo can deal with it.
You'll have to let Majin rest for now, while you figure out how to escape. Even if you managed to get out of here, you'd need tea to survive, and you're currently only being given the bare minimum. But then, Shusha lets out that if it's tea you need, she has lots in her bag. Turns out Okita had packed a lot of tea for Shusha before the battle "just in case". Nobu now realizes that Okita didn't desert them (although she could've totally still had a stomach ache since she's sick all the time), but she was planning for this all along. With this, you'll last for several days. Now you just need to contact Chaldea, so you ask Iyo if she can contact Himiko directly, like Himiko did for you earlier. Iyo says she doesn't have that kind of skill, and you urge her to just try her best because she'll never know unless she tries, and so she does, and...it doesn't work. Then again, if she had the same kind of power as Himiko, then Yamataikoku would've probably never fallen.
Just then, Kuko appears, asking Iyo and Shusha to come with him. They follow him, so as to not cause any trouble for the rest of you. You consider whether you should just drag Majin's body along, but then you hear her voice, stating that "the adjustments are finally done", as she stands up, now in her first ascension outfit instead.

Mitsunari is ready to usher in Hideyori. Kuko says the priestess and the sacrifice have both been sent to the altar, so all that remains is to conclude the ritual. Mitsunari feels compelled to thank Yamanami for all he accomplished for them here. But she knows how he must feel. For most people, compassion trumps reason; no different from beasts. People might speak highly of loyalty and the likes, but in the end it's all about the self. Every person is a masked beast, waiting for the opportunity to betray the world. That's why Mitsunari is such a stickler for the law, to bind the beastly nature of men. Still, he doesn't need the others to agree with or see his reasoning; he knows what's right and what needs to be done. With that, they leave for the altar, to resurrect the ancestral beast of Kunakoku, and for the advent of the new lord of the Toyotomi clan.
In the dungeon, Rikyu has brought Akesato some tea. The latter seems pretty chummy with Rikyu, all things considered. Seems that all she remembers is dying and then appearing here, but she does love the tea. Rikyu also seems to be this friendly in case there's ever a situation where they can help each other out later on. Akesato asks for some food, and Rikyu says she'll be back with some after she attends some other business. Akesato does, however, seem to realize Rikyu has some ulterior motive. In the end, all she can think about is Yamanami, and how he never came back to her after that day, perhaps because he died. Suddenly, Okita appears to have sneaked into the dungeon, introducing herself as a friend of Yamanami.
Back in Chaldea, in the infirmary, Chacha has woken up again. She asks Mori if he thinks Mitsunari holds a grudge against her. Mori doesn't seem to think so, considering how Mitsunari took it upon himself to fight Ieyasu at Sekigahara. Surely it would have been the opposite if there was a grudge to be held. But she elaborates, saying it would be because while Mitsunari said he would fight for Toyotomi, Chacha refused to involve Hideyori in the conflict. Because of that, Mitsunari was left alone to fight. That battle was the beginning of the downfall of Toyotomi, and in the end, at Osaka Castle, Hideyori had to die because of Chacha. Mori seems to think that doesn't matter, it only matters what happens next. Chacha feels that she has a responsibility to fulfill here by going to Hideyori and Mitsunari, and with that, Mori tells her to be on her way, then. Hajime enters the room, declaring Gudao is in danger, and that the Shinsengumi will support Chacha in the operation.
On the bridge, Da Vinci explains that they can only send three people as reinforcements. Chacha insists she has to go, and when asked about the wound, she says Mori took it easy on her so she's fine, but he interjects, saying he didn't go easy on her, it's just that mothers who act for their children are practically unstoppable. Hajime will join in as escort for Chacha, and the third Servant will be Himiko, considering it's Yamataikoku and now there's Iyo as well. For a bit, Mashu seems reluctant to send Chacha to take care of Gudao, but eventually concedes, wishing her luck with both Gudao and her son.
To deal with the atmosphere of the Singularity, Da Vinci has engineered a sort of forcefield they can deploy. Now, they're ready for reishifting, except, as Hijikata points out, there's the matter of the coordinates...

We appear to get a flashback to the time just before Rikyu committing seppuku. An official is there to get them, but they only speaks about how unfair this is. The official, however, only says that the crimes of bribery for their own profit were clearly exposed by Mitsunari. But Rikyu won't have it. Screw Mitsunari, and screw Hideyoshi too if he's gonna act like this. What's wrong with a merchant making money for themselves? This world Hideyoshi is creating, a world without war, it will reduce the people's faith in him, and eventually they will come for him, they say. The official puts an end to their ranting, and they cut their belly clean across. (I should point out for the sake of theories here that Rikyu in this scene doesn't have a sprite.)
The scene draws Rikyu's farewell poem on screen:
"I raise the sword, this sword is mine, long in my possession, the time is come at last! Skyward I throw it up!"
(original TL Suzuki Daisetsu)
Amidst the pain of cutting one's own guts, and seeing them spill out, Rikyu appears to descend into madness. In the blood spilling out, Rikyu sees the corpses of a discarded monkey and a dog. "Fear and tremble the setting sun," they say. Monkeys and dogs alike should fear the sun setting over hell.
The official deems Rikyu it an unseemly sight, and someone is ordered to cut Rikyu down once and for all.
This was Tensho era, 19th year, 2nd month, 28th day (April 21st, 1591). Sen-no-Rikyu's seppuku.

Back in the singularity, Mitsunari and co are nearing the place where the ancestral beast was sealed. Mitsunari explains to Iyo that they're to be sacrificed to awaken the ancient god, and that originally back in the day it would've just been Iyo, before Himiko intervened and ruined everything. Shusha is apparently added now because Rikyu had told Kukochihiko that the beast god prefers the "children of men". Rikyu says Shusha exhibits the best traits for this, and says Mitsunari would surely understand, but Mitsunaria merely says he doesn't know the requirements for this, and doesn't care as long as it fulfills their goal.
Soon enough, Chaldea will walk into this trap, he says, and just as well, Chacha enters right then. Chacha asks for Hideyori, and Mitsunari says he'll be here soon enough, now that the last sacrifice is here. Chacha is embraced by darkness, unable to move. Mitsunari makes some quip about how Chacha's demeanor turned the people away at Osaka, but soon enough they realize something is wrong. Surely, Chacha didn't come here alone from Chaldea. Chacha says that Mitsunari never was that great of a fighter, and especially not when they couldn't notice this much. Hajime appears behind Mitsunari, and probably takes him hostage (hard to tell just from the sprites tbh). Kuko moves in to stop them, but Yamanami blocks his advance. Mitsunari asks Yamanami if he knows what this means, to which he simply responds that he does, and then calls out Okita from hiding. She has already evacuated Akesato to somewhere safe. Apparently even Hajime is here because of some directions from Yamanami (which I guess was subtly hinted at in the other scene, idk), and he is then quick to grab Shusha and get her to safety. Shusha thanks the shady old man, and Mitsunari tells Kuko to perform the ritual with just Iyo. But Himiko bursts in next, apologizing for being late. Since they apparently knew from Yamanami's words that this would be a setup, Hajime and Himiko shifted the coordinates a bit, and circled around the area first. Chacha was just bait, after all.
Mitsunari asks Kuko and Rikyu to help, but Rikyu seems to have other plans. Such a pathetic display, truly. So confident in victory, Mitsunari went ahead with the plan, only to find himself surrounded by traitors again. It really is Sekigahara all over again. In the end, no one will follow a person like Mitsunari. Who would dare tear a country apart under someone of such mediocre skill? Mitsunari attempts to cut down Rikyu, but his sword passes through their body completely, shifting amidst black mud. While Rikyu quips about how Mitsunari can't even put a mere tea master down, Hajime suggests you get away while the enemies are fighting amongst themselves.
But Yamanami and Okita are both stuck. It's not the darkness this time, but something heavier. Rikyu says she hopes you will all enjoy the tea ceremony and entertainment she has prepared for you.
Sen no Rikyu:
Yes, the execution of Toyotomi Hideyoshi's head of the Go-Bugyō---
Jibu-no-sho, Ishida Mitsunari.
I speak on behalf of all of Japan when I ask that you, Ishida Mitsunari, atone for your sins here and now.
Mitsunari says he's hardly the one who Rikyu should be punishing. The order for seppuku was based on her own misdeeds, and issued by Hideyoshi himself. But Rikyu merely reiterates, as if Mitsunari didn't understand what was being said: she is speaking on behalf of all the people in the land. Once more, Mitsunari seems to think this is some maniacal representation from Rikyu's side, and Rikyu can't believe he's so dense.
Sen no Rikyu:
Are you really saying you did not notice as soon as you saw this face? I guess that's a given.
But seeing it now, can you still make high claims about all your justice?
The black mud engulfs Rikyu, and she turns into the girl we've seen two times past. Mitsunari wonders what's going on, but Rikyu asks if he really still doesn't recognize her face. But he does. He's definitely seen that face somewhere before. Finally, he remembers.
Sen no Rikyu:
By order of your Lord, the emperor, you had me executed, treated like nothing more than an animal---
I am Komahime of the Dewa province.
