Kuchimoto ni Akai no Tsuitemasu
口元に赤いのついてます
Akito is a skilled beast hunter, considered among the top in his profession. He has pursued a specific goal for an extended period—eliminating the vampire known as Adam. Despite repeated attempts, he has been unsuccessful. Akito attributes this failure to Adam's high level of experience and strength, which he believes makes the vampire a formidable opponent.
