I was watching this episode and heard a familiar sound. It reminded me of another anime, but I forgot which one. It is in Episode 490 of Naruto Shippuuden starting at 11:48. It is when Hinoko is sitting on the stairs and the other kid went up to him, and the music starts playing soon after. The music starts when she starts creating the little sphere of chakra or whatever. I just want to know the name of the music.
