Shikkoku no Neue Seele

A glowing object resembling a meteor crashes from the sky, resulting in the death of Ryunosuke, one of the Fuwa brothers. His sibling, Kotaro, discovers his brother's remains and is shocked to learn that Ryunosuke has been reborn as a female character from a manga. The same object continues to fall across Japan, an event later referred to as Dream Showers. This phenomenon marks the start of a period of widespread chaos.
