Shiki

Shiki is a Lich and presently in servitude to Makoto Misumi.

His origins and original name are unknown. What is easily ascertained is that he was a brilliant researcher in magic knowledge. Before his death he possibly came back as a lich or possibly, he turned himself into a lich; when and where is unknown. All that is known is that he’s been a lich for a very long time and with quite the reputation.
