Himawari!

Himawari Hinata enters a ninja school inspired by the mysterious rescuer who saved her as a child. She is determined to become a capable kunoichi, even when her enthusiasm runs ahead of her skills.

Her new teacher Hayato knows little about the strange community around him, yet he bears a mark resembling her rescuer's. As Himawari trains alongside talented classmates, her interest in him connects ordinary school troubles with questions about her own past.
