Masamune Makabe

Maa-kun, Piggy, 真壁政宗

Masamune Makabe is an arrogant young man consumed by the desire for vengeance. His targets are none other than the well-liked and affluent Adagaki Aki. Although his appearance has improved, he was previously overweight and often subjected to ridicule from others.

Spoilers:

It shown later on that the reason he hates Adagaki Aki so much was because she rejected his feelings for her and nicked named him "Piggy." Deathly afraid of spiders, as when one landed right in front of his face he dropped his "cool" act and screamed. This is one of the fears he couldnt conquer when he was working on recreating his character. Later on in the story, in order to get revenge on Aki, Makabe teams up with Koiwai Yoshino, Akis maid.
