Chisato y Takina han vuelto de Hawái para seguir su trabajo en el Café LycoReco. Todo marchaba bien hasta que Chisato le hace una propuesta algo especial, revolucionando por completo el vínculo que tenían hasta ahora. Y dejándole el corazón en la garganta. Yuri. Chisataki. One-shot

5 years before the event of the main story, an incident in central Africa regarding weapons of mass destruction turned into an effort of the rebellion of a specific Lilybell unit towards DA. To clear their name, One of the units listed as traitors decided to eliminate the true antagonist with the help of a certain boy who lived on the battlefield. Will it be their heaven or hell?

After the Enkuuboku incident, Chisato is saved with a new artificial heart. But things are not immediately smooth-sailing.

Una pequeña historia de como Takina entrego su regalo de cumpleaños a Chisato, aunque es de todo menos un regalo.

"Like a contagious disease, or some mushroom spores, the more she's around Chisato the more she feels the need to keep being near Chisato. It's a tingling in her fingers begging to grab a hold of some part of the girl: a hand, an elbow, that throat. It's a bite of her own lips to keep from trying to bite Chisato's. It's a yearning for less space and more time."

While cleaning Chisato's room Takina finds some items she is unfamiliar with and asks for guidance.

A simple mission goes very wrong when Takina shoots Chisato by mistake.
