Maken-Ki! Battling Venus

Like Rain on a Sunny Day (1x6)

:

The return of the rainy season causes Inaho to experience flashbacks to the time when she met Takeru eight years earlier. She wants him to remember it too, but he can't. Despondent, she wanders off in the rain where she discovers a cat that she names Monji (文字?) for the cross on his head. Monji runs off and is saved from rockfall by Takeru, who is searching for Inaho, who saves him in turn. Takeru still can't remember his promise, but he unwittingly repeats it while apologizing, so Inaho is satisfied.
