Yuuki

He has made some self-righteous remarks, however, he's very eager to learn new things and extremely enthusiastic about training. (16-44)

His desires for acknowledgment might be a bit stronger than others, but well, he's generally a good kid. His tendency to get hasty is not unlike Meiko, but I'm sure it can be fixed so long others care for it. Compared with Hayato Masaki.

Initially he went around randomly spewing flames everywhere like a pyromaniac, but once we put him with some reliable attendants, he's gotten a better.

Satou thought that Hero Seigi also had some dependable attendants with him.

Since Hero Yuuki's range is pretty expansive, cities and the populaces often suffer collateral damage whenever he does it near a city, so he's not really liked.

Background
There's four heroes that got summoned (Meiko, Yuuki, Seigi and Fuu). (16-42)

Equipment

 * Holy sword Laevateinn (BURN DOWN Laevateinn) (16-44)

Plot
Hero Yuuki is holding a bizarre rivalry with the demon lord slayer Satou. (16-44)

Hero Yuuki attendants are numerous. Unlike with other heroes, many are of level 30.

The firepower of the flame the Hero unleash probably surpasses even the forbidden spell of flame magic, [White Inferno].
