The Bloodthirsty Blade
The Muramasa
Caster's bread and butter Noble Phantasm, this is his basic Katana design that was so efficient and made him famous through out the land as one of the greatest blacksmiths in his country history. The blade will then adopt its creator namesake becoming the "definition" of his legend. The sword was known to be a cursed blade that once unsheathed needed to taste blood, be from its owner or his enemies, to go back to its sheath. At first glance the Muramasa is just a regular sized Katana locked inside its scabbard. Much like any other blade to draw the sword the owner just needs to grip its hilt and pull the blade, but differently from other swords Muramasa's hilt is covered with microscopic needles that pierce and suck the blood of its user once he unsheathes the blade. The sword fueled by its owner blood, will begin to empower him, raising his stats slowly. The more his owner uses that blade and the more it lets it drink blood, the bigger are its stats raises. Additionally the sword's blade also has a similar function to its hilt, being able to drink the blood from an enemy cut by it. The blood of an enemy will add to the stats raising effect and as an additional effect will begin to repair the blade from any damage that it has suffered during battle.
A nonservant combatent who is empowered by a Muramasa that has drink enough blood could theoretically be able to fight against a servant in melee combat even if on the defensive, or even surpass it depending on the strength of the blood so far.
As his basic noble phantasm and the source of his legend, Muramasa is able to manufacture Muramasa faster than his other works, only needing a few minutes to make one.

To sever heads and butterflies
Juuchi Yosamu
Muramasa ultimate design for a sword, its something he never actually made. Created on an old storytale that puts the two great swordsmiths of Japan at odds: Masamune in this story as the old experienced master and Muramasa as his temperamental cocky pupil, but in truth those two masters have never met each other during their lives. In that storytale Muramasa tired of living in his masters shadow, challenges the old Masamune to a duel to prove that he is able to make the finer sword of two. They both worked tirelessly and eventually, when both swords were finished, they decided to test the results. The contest was for each to suspend the blades in a small creek with the cutting edge facing the current. Muramasa's sword, the Juuchi Yosamu (十千夜寒?, "10,000 Cold Nights") cut everything that passed its way; fish, leaves floating down the river, the very air which blew on it. Highly impressed with his pupil's work, Masamune lowered his sword, the Yawarakai-Te (柔らかい手?, "Tender Hands"), into the current and waited patiently. Not a leaf was cut, the fish swam right up to it, and the air hissed as it gently blew by the blade. After a while, Muramasa began to scoff at his master for his apparent lack of skill in the making of his sword. Smiling to himself, Masamune pulled up his sword, dried it, and sheathed it. All the while, Muramasa was heckling him for his sword's inability to cut anything. A monk, who had been watching the whole ordeal, walked over and bowed low to the two sword masters. He then began to explain what he had seen.
"The first of the swords was by all accounts a fine sword, however it is a blood thirsty, evil blade, as it does not discriminate as to who or what it will cut. It may just as well be cutting down butterflies as severing heads. The second was by far the finer of the two, as it does not needlessly cut that which is innocent and undeserving."
This blade blueprints while its something that Muramasa has never created personally, thanks to his Innocent Monster skill it was something that he gained post-mortem. To create this word Caster needs to spend entire days completely focused on the creation of his ultimate sword. At the end of the initial process using many different materials from around the world to create the blade Caster will then bath the blade with the blood of whomever he wants to be the owner and his own and then leave an entire night under the moonlight. After that step is done the sword's blade will become completely dark much like the night, and its from there that comes its name, and the user chosen by Caster will be able to use the weapon.Differently from his Muramasa sword that can be used by anyone anywhere, Juuchi Yosamu is a special blade that can only be used by a single person besides Caster decided during the creation process. The Sword once completed is actually a conceptual weapon carrying the concept of "to cut through". The blade has the ability of impose that concept into anything. Objects, living beings, other conceptual weapons, magic and even reality marbles. As long as the user user is in range, the Katana will cut through that indiscriminately.
Though while extremely powerful, Juuchi Yosamu will lose that ability after a single attack losing its dark color becoming "only" a very sharp B-ranked Noble Phantasm , and has to once again have its owner blood bathed in it and spend an entire night under the moonlight to recharge that attack once again
