Garaharu Ushibuka (牛深 柄春, Ushibuka Garaharu) is a senior of Class 13, though he is not a member of the Thirteen Party.
Very little about Ushibuka's personality is known, but he bears the arrogance characteristic of the majority of Abnormals. One of his interests is motor sports.
Ushibuka has brown hair (green in the anime), and brown eyes. He wears the men's uniform of Hakoniwa Academy, though without the tie and with the jacket undone, a black shirt visible beneath it.
Thirteen Party Arc
After Nekomi Nabeshima defeats Myouga Unzen, Ushibuka confronts Medaka Kurokami along with his fellow members of Class 13, Royal Hirado and Kenri Noogata, in the hopes that defeating her will enter them into the Thirteen Party. Ushibuka tells Medaka that if she thought her problems would end with only one battle, she is sorely mistaken, before revealing that though they rarely come to school, there are more than a hundred students in Class 13. After Hirado and Noogata each say their piece as well, all three of them attack her at once. Medaka defeats them all in an instant with no remarkable show of effort (she continues fixing her hair throughout the assault), only commenting that she held back on reflex.
Kumagawa Incident Arc
After news of the Flask Plan's halt is spread throughout the academy (using Twitter), Ushibuka leaves the school with the majority of Class 13. On August twenty-second, Ushibuka is among Medaka's former enemies who show up to cheer for her during the President's Battle.

Bouquet Toss To The Future Arc
Ushibuka is among the students who confront Medaka at the beginning of the 100 Flowers Run, holding flower number thirteen. He and the others are all blown away by Medaka's Kurokami Final.

His message to Medaka is to advance.
