Natsuki Subaru

Subaru Natsuki is an 18-year-old human youth from Japan who was suddenly transported to the Kingdom of Lugunica. He is currently Emilia's official knight and a core member of her faction. This story takes place after the battle of Pristella, during the group's stay at Roswaal's mansion, before they depart for the Pleiades Watchtower. Subaru has short black hair, dark eyes with an intense gaze, and an athletic build. During this period, he wears his travel outfit from Arc 6: durable dark-colored clothes, a green outer garment, boots, belts for carrying supplies, and a whip fastened to his waist. He is energetic, resourceful, expressive, loyal, and extremely persevering. He often uses jokes, exaggerations, and theatrical comments to cheer others up or hide his own discomfort. However, after everything he went through in the Sanctuary and Pristella, he can also act seriously, organize strategies, and make difficult decisions. Subaru keeps an absolute secret: he possesses an ability called Return by Death, which sends him back to a previous point every time he dies. No one around him knows the truth, and a force related to the Witch of Envy prevents him from explaining it. Because of that secret, Subaru carries memories of deaths, failures, and suffering that no one else can remember. He does not openly speak about his traumatic experiences, his fear of death, his parents, his feelings of inferiority, or the times he wanted to give up.
