Bungo Stray Dogs: Elegy for Tokoyami Island

At first, she only wanted to understand one person. She never expected that person could also become the key that opened the door to another world.

She fought on the desperate battlefield of Tokoyami Island, called out a certain “optimal solution” AI, and became a source of support for “Arahabaki” and a teacher to the “Stray Dog Without a Heart.”

Though their faces looked alike, no matter how you looked at it, she didn't seem like the sister of that coldhearted man.

She seemed especially guileless, the opposite of Mori in every way, and rarely lied. According to the famously anonymous Dazai, that was because she considered lying beneath her.

She seemed to have incredible patience with anyone under eighteen. According to the famously anonymous Akutagawa, she treated him as if time had been reversed: in the first few years after they met, she acted as if they had known each other for ages, but after he became an adult, she treated him like a stranger and started getting to know him all over again.

P.S. OOC is inevitable, since this isn't the original work.
