Himawari!!

Having renewed her pledge to protect her teacher Hayato, Himawari resumes training with her fellow students at Shinobi Academy. Their noisy, often clumsy routines continue, unaware that a mysterious organization is closing in on the school.

The new threat brings questions about Himawari and Hayato's past into the open. Protecting the person she serves now demands more than enthusiasm, as the bonds formed during her training face a genuine test.
