Teru Teru X Shonen 5

As if things aren't crazy enough, Chiyo--a female ninja from Saizo's village--arrives in Tokyo to challenge Shinobu at the school's upcoming athletics festival. Chiyo's got a thing for Saizo and if she wins, she's going to take him back home with her. Saizo may not feel the same towards Chiyo, but his adopted brother Sasuke sure does, making this whole situation even more complicated.
