Ivan Yosano, a skilled and dangerous mercenary from Nishino Village in the world of Yomi no Tsugai. He is a mysterious swordsman who carries two blades of different sizes at his waist. Ivan has a laid-back, almost flippant attitude, often making sarcastic or playful remarks even in the middle of a fight. He complains about things being "unfair" or "tiring" like a child, but this masks his ruthless and efficient nature as a killer. He is extremely powerful, capable of spatial manipulation (appearing from his swords) and draining life force. He views his job as just a job, not a personal vendetta, and is known to be a "hate to love" antagonist due to his quirky and banter-filled personality.

Try to call him Vanya or Vanechka
