(Add later)

It all started with an accidental, late night visit by Akko. Diana was awoken by Akko knocking something over in the dark and almost breaking it. Akko was testing herself in controlling her animal shifting spell and accidentally got lost in the school's ventilation system and found her way into Diana's dorm room. After Diana threw Akko out of her dorm, she couldn't help but find Akko's mouse form cute. But, she denies herself against this. Diana, as the days go on, begins to realize, and deny, her love for Akko. But Diana, sure enough, stops her denying. Does Diana win Akko's heart, or will someone else? ;)

A series of one-shots brought to you by Diakko.
