The protagonist of the story. He’s originally a student from a peaceful world, but one day he wakes up in a completely different parallel world. He spends the next three years as a soldier in this world where a war with BETA rages on, but tragically dies in battle. He awakens once again, back to the same day when he first found himself in the parallel world. This time around, using all of his past experiences and memories from the previous loop, Takeru will fight until mankind is saved.

Takeru’s neighbor and childhood friend. She’s exceedingly cheerful and is a busybody. Takeru doesn’t see her in the parallel world he wakes up in.

She excels at close combat and is particularly skilled with a sword. She comes from high nobility and has a calm and centered personality. It seems that her family’s lineage stems from one of the prominent empires, but much remains unknown.

The squad leader of Takeru’s training platoon. She’s strict and very by-the-book as well as particular about principles and standpoints. Her nickname is “Class President.”

She keeps to herself and is vague when she speaks. She’s always calm and level-headed, but she places importance on being able to adapt to the situation, which tends to lead to a lack of cooperativeness.

At first glance, she seems weak and unreliable, but even though she naturally gets extreme stage fright, she has overcome this flaw through hard work and dedication. She’s skilled in long-range combat and is the top shooter in the Far East.

The mood maker of the training platoon who always does things at her own pace. She has excellent survival skills and is extremely capable at handling crises.
