1x12 - Ichigo Aika: Strawberry Elegy

Aika boldly barges in on Kouta's bath time, holding a trendy bath bomb. Meanwhile, Kouta, concerned by Aika's tears he saw in the ruins, blurts out something that spoils the mood. However, Aika's reaction was different from what Kouta had expected. Sensing something, Kouta asks Aika to tell him about herself. Then, Aika begins to recount a certain event from her past.
