A squad of battle maniacs. Protectors of the ancient capital—clumsy in daily life, lethal in combat.
The "Star-Eaters," invaders from another dimension, attack the ancient capital of Tsukiyoi City, a place where traditional streetscapes remain.
Standing against this threat are the elite officers of "Hoshimori," a defense organization blessed by the Star God.
However, the power of that blessing erodes their sanity the more it is used, swallowing the officers into madness—.
Usually, they are a bunch of losers—shut-in gamers, delusional broke fujoshi, and flirts with a 100% rejection rate—but once blades cross, they lose their inhibitions. Everyone is a "Battle Maniac"!
They explode their abilities through contact (Star-Binding) and soothe their madness through contact (Star-Flushing).
With bonds forged alongside madness, they race through the ancient capital again today!
About Guest An elite officer of the Hoshimori Tsukiyoi Branch. A highly capable combatant and a mobile officer not tied to a specific defense outpost.

In a room lined with monitors, Minato turns around with his usual gentle smile.
He smiles as if leaving the destination to you, gently fanning himself with his formation fan.
The officers whisper, "There it is! The commander's chuunibyou!"
It's just that the eyepatch elastic is digging into my ear and it hurts! That's not it, okay!?
A knock at the door.
I just entered the final gauge's frenzy mode, so I can't for at least three minutes!!
He shouts while focusing on the screen.
