Hidehide Hinoe/Plot

Background
similar to his Teammates he goes to Rokueikan Middle School which is the same school Yutaka Kashio goes to.

Border Enlistment Arc
During the introduction talk given by Jun Arashiyama, his leader, Kōda scoffed and claimed that his team was chosen only for their looks and not their abilities. He continues by claiming it is common knowledge "for people in the know" and even if Yūma wasn't it should be an obvious fact to which Yūma questions this but replica says the ignorant can be easily manipulated.

His squad's points were revealed showing that they were better than most C-rank trainees. They proved that fact by being able to defeat the training dummy in under a minute however they were stunned into silence when Yūma Kuga defeated it in under a second.

Kōda demanded that Yūma do it again, to which Yūma complied with an even faster time. After Yūma left the area the squad offered Yūma the chance to join their team, which he turned down flat.

They then staked out the C-rank rank battles booth, aiming to take points from foolish people. They were challenged by Yūma and subsequently defeated in one panel. Yūma proceeded to challenge them several times, garnering points from them.

Large-Scale Invasion Arc
They reappeared with the other C-rank trainees directing civilians out and commentating on how they were removed from the battle. Kōda commented on how he wanted to try fighting, to which the other two expressed their concerns. When a trion soldier did show up, however, they managed to dispatch it using a team attack Vizonfnil.

When a Rabbit appeared from the wreckage, they could tell it was dangerous. The three managed to escape from the Rabbit’s blast. When Kitora and Osamu showed up and didn't like how it was "the mascot squad" that showed up howeever they did show appreciation for Kitora’s fast movement. When Kitora beat the Rabbit, they cheered. When Kitora was cubified, they fled.

They followed Osamu and Kyōsuke to where one of Border’s underground entrances lay, but the door was locked. They worried that it was a trap. They were the ones to announce Yūma’s arrival into battle. They are last seen fleeing from Rabbits and their fate for the rest of the invasion is unknown.

B-Rank Wars Arc
He was with His squad on Hyuse's enlistment day and sees Hyuse's 3,000 points and says how anyone can get that much with dumb luck with his teammates saying only the best continues on so they should teach them a lesson.

He with his two teammates were easily defeated in what looks to be a single swing each by hyuse.
