Shikimori's Not Just a Cutie manga volume 5 features story and art by Keigo Maki.

Shikimori spends some quality time with her rival (?) Kamiya and finds that they have a lot more in common than just their attraction to Izumi. Could this be the start of a special friendship? With the culture fair now over, the time has come for the dreaded (to some) sports fair, and the whole gang has been assigned to the relay race team! Hachimitsu, whose interest in sports and all physical activities is nonexistent, faces a difficult dilemma. Her friends are passionate about competing to win, while she is passionate about not exerting herself in any way. Will the power of friendship overcome her deep distaste for running or, heaven forbid, practicing running?!
