Kischur Zelretch Schweinorg

Height: 185cm

Also known as the Wizard Marshall, Zelretch of the Jewel, and the Kaleidoscope.
One of the five True Magicians.
He also had a role as one of the Dead Apostle Ancestors, but because it was not relevant to the story of Fate, that part was cut.
A magus who was symbolized by gem stones. An eccentric old man who raged at evil with a passion, but laughed at do-gooders.
He frequently took in pupils, but no mage house had emerged as successors to take over his mantle.
Once upon a time, he engaged the King of Vampires in single combat. He pushed back a boulder falling from the heavens in a feat of power. Such a monster was Zelretch.
However, since then he had aged significantly. It seemed that he could no longer wield Magic the way he did, back when he was at his prime.

Fate/Stay Night: Heavens Feel
Zelretch appears before Rin Tohsaka at the Clock Tower after she manages to recreate his Jeweled Sword with the assistance of Shirou Emiya during the Heaven's Feel route, complimenting her accomplishment by taking her as a protege and having the charges against her nullified. He had expected the least out of Nagato's unremarkable bloodline, ruminating on the progression of the Tohsaka family in just six generations. In the True End, he uses his influence in the Clock Tower to get Rin acquitted of opening and closing the gate of the Greater Grail.

He makes a brief cameo appearance in Carnival Phantasm.

In Fate/Kaleid Liner Prisma illya Zelretch is the creator of Magical Ruby and Magical Sapphire. He gives them to Rin and Luvia so they can retrieve the Class Cards. He appears briefly conversing with Waver Velvet/Lord El Melloi II.
