Sugiyama-senpai's Secret

Synopsis

On the morning of the opening ceremony, Yume dreams that she's collected Dreamy Stones to fill the Dreamy Box. In the dream, the Queen says she'll grant Yume's wish as promised... but at the same time, she tells them that Yume and Mew will no longer be Dream Partners! Horrified, Yume jolts awake mid-dream. She can't get the dream out of her head and zones out at school... Meanwhile, Sugiyama-senpai receives contact from 'someone' in America. It's from her younger brother Akihito, nicknamed 'Akki,' who was studying abroad... And it turns out Akki is actually an incredible genius little brother!
