[Western Crossover] Diary of a Savior in the Making

#Protagonist: Ritsuka

A story about amnesia, turning into a little kid, a broken mirror brought back together (?), saving the world, heroes gathering, and raising and raising and raising.

What if two brothers grew up together, one was taken away to save humanity, and the other became a city hero? Fifteen years later, they reunite with no memories, in a story full of both ordinary and extraordinary days.

This story is expected to go premium on March 10, 2026. Thank you for your support.

A new resident suddenly arrives at an abandoned villa in the outskirts of Gotham.

A child and a young butler.

The child keeps to himself, and no one has ever seen him.

The butler seems very professional, though so professional that you can’t help wondering if he has some kind of side job.

The strange pair catches Red Robin’s attention.

But he never expects that a case he investigates with Bruce will lead to a hidden truth: an uncle he has never met, Bruce’s brother, became a victim of human experimentation, and they knew nothing about it.

The mystery he had thought remained unsolved seemed destined to become a regret forever.

Until one day, he catches sight of the neighbor’s child by chance, and sees Ritsuka’s face, so similar to Bruce’s.

tips:

1. Male protagonist, no romance. Everyone helps raise Ritsuka, an amnesiac savior of the world.

2. Chaldea is at max bond. All members of Team A, the Director, and the Doctor survive.

3. Not your typical Batfamily story. Bruce’s younger brother grew up with him before leaving to gain experience, but is now Ritsuka Lily.

4. Although the idea started with the neighboring IF story, this one has little to do with it and contains lots of Type-Moon background lore.

Theme: The future holds infinite possibilities.
