Guy was a member of the Empire's Assassination group appearing in the prequel series Akame ga Kill! Zero.
Guy is a tall young man with a sturdy and muscular build. He has short brown hair and a scar on his left cheek. He wears a brown vest with white sleeves and a white collar. His pants are also white.
He is shown to be rather perverted, frequently visiting brothels whenever his team goes to a village. Furthermore, he was shown to be looking at the hem of Akame's dress, which she received from Martha. He also challenged his teammate Cornelia to a grappling contest, which was actually an attempt to "accidentally" touch her. Despite this, it appears that he has feelings for Cornelia. It is implied that he asked her to be his girlfriend at least once. When she died, he was enraged, vowing to avenge her death by killing the Oarburgh clan.
Guy was one of the many children that was sold to The Empire. He was picked to be put through a test in order to select candidates for The Empire's assassins. He was ranked second among the candidates and got into the Elite Seven. Sometime before his first mission, he fell in love with Cornelia. However, she turned him down.
He is seen mining for precious crystals, which are identified by Green. He complains that Cornelia won't pay any attention to him and states that he wants to spend his earnings on prostitutes. Green declines his invitation to come along. Guy goes over his time limit in the brothel and is tied to a tree branch upside down. He is found by Akame, who cuts him loose. On the way back to their hideout, he is kicked in the face by Akame when he attempts to look up her dress.
After Taeko, Chelsea and Babara came to assassinate Elite Seven, Guy with other members of Elite Seven killed Tengu Mercenaries, while Oarburghs run away. Later at the hot springs, Najasho and Green tied Guy to the tree, so he couldn't go looking at girls.Because Chelsea discovered true identity of Najasho and Green, Gozuki decided to keep all boys from Elite Seven outside of town, while girls stayed in Deng Zhi Town Inn. Later, when Guy with Cornelia went to the Gozuki hideout, Chelsea was spying on them. Because of that, Babara Oarburgh attacked male squad of Elite Seven. She easily blocked the blows of Najasho, Green and Guy but she couldn't stand power of Gozuki's teigu - Murasame. After assassinating Babara and Taeko, Buy learned that Cornelia died. He promised to avenge her death by killing the Oarburgh clan.
After some time Elite Seven got new mission. They had to help Group of Terror to kill Gravekeepers and got their treasures. While he was going to help captured comrades, he came across many Gravekeepers, Ragu among others, but he easily killed them. When he finally came to rescue Group of Terror members and Tsukushi, he met Weneg - Gravekeepers Boss. Guy couldn't defeat him which resulted with Guy' death.
His Shingu is Rare Suit, a suit of armor that can manipulate soil. Its biggest advantage is burrowing underground, which can be used to surprise attack unaware foes. However, using it puts great strain on the user's body and it is unable to create soil out of nothing. Like the other members of the Elite Seven, he is immune to most poisons.
- Guy is the physically strongest member of the Elite Seven.
- Guy wants to one day surpass Najasho and become kill rank No. 1.
