Akito was in a boy group, named SEK4_I. 4 members, him, Tenma Tsukasa, Kamishiro Rui and Aoyagi Touya. They were a group that wanted to surpass the legendary concert—ラド WEEKEND—while making everyone smile.

It wasnt all smiles, though.

He has a huge rivalry against the group, (143)-GIRLS! Specifically, the idol, Shiraishi An.

After their groups keep getting nominated for awards against eachother and compared to the other, a rivalry forms between the two groups, and they often clash and bully each other. One time, during an award show, An's group won an award against Akitos, and in her speech, she said: "Our opponents are mostly call good. Im just not a fan of big bangs. They scare me."

Big bang is one of the songs Akitos group has released and is on the album nominated for the award they lost. After that, Akito 'accidentally' threw red wine at An whilst she was on stage.

Constantly dissing eachother in songs they wrote, liking twitter posts of slander against the other, making really rude statements. It was war.
