Onigawara is the fictitious student council president at Aki and Misao's school and a supporting character in the Misao game who guides the player in the same manner as Library.

Strangely enough, even when the school comes under Misao's curse, Onigawara continues to act in a calm and courteous fashion befitting a student council president. Thus, it should be noted that Onigawara doesn't seem the type to be easily fazed, since he wasn't very surprised or affected by what was happening to the school during the game's events. (This could be, however, an allusion that Onigawara knew it was going to happen, or was more involved than originally seen.)
