Abilities
Isemi is a "living dead" Master whose body is thoroughly devastated. His every heartbeat causes pain, and each breath drawn is like swallowing needles. He is constantly drowning in pain without a sense of living. Summoning a Servant is enough to drain his life, limiting his time as a Master to one week before he dies.
