Suwa is a B-Rank agent and the leader of Suwa Squad (B-rank #12).

He is loud, with a bombastic personality that reacts in a big way to everything. He is vulgar and assertive but very approachable and without pretenses, and quick to get comfortable around. When in combat, he has a tendency to be reckless and enjoys teasing opponents and riling them up. He has a cigarette in his trion body, just to show off, since it isn't even lit.

Suwa is capable of leading his squad effectively, unifying it with his personality. His strategic style is notoriously audacious and high risk, high reward in nature. When his gambles pay off, however, his tactics have the potential to defeat Squads from the upper tier of B-rank. He relies on the high attack power of his dual shotguns and the support of his teammates to blast the opponent away after they get in range.

One day, a gate to another world suddenly opens in Mikado City. Aliens invincible to Earth’s weapons, called “Neighbors”, start coming over. Earth’s only line of defense is a mysterious group called the “Border” who are armed with weapons called “Triggers”. 
 
Four years later, the city has recovered from initial attacks and citizens of Mikado City have started to get used to the Neighbor’s attacks. Yuma Kuga, a transfer student, and his classmate Osamu Mikumo find themselves fighting a Neighbor that suddenly appears. Osamu, who is actually a Border agent, activates his Trigger but is unable to defeat it. This leaves Yuma to activate his own Trigger and defeat the alien. Yuma reveals that he is not part of Border and is actually a Neighbor who has transferred from the other side.
