Sendou Takahisa
Takahisa is the hero of Centostella kingdom, though he didn't exactly volunteer for the job. He got summoned to this other world alongside his senior Sumeragi Satsuki, who became the hero of the neighboring kingdom instead. The summoning was a package deal—it dragged along three other people too: his two siblings Sendou Aki and Masato, plus his friend Ayase Miharu.
Being thrust into a hero role with most of his inner circle already there is probably the only reason Takahisa hasn't completely lost it. Satsuki, at least, ended up in a similar boat as the hero of her own kingdom, so they're dealing with comparable pressure. As for the others, they're just trying to figure out their place in this new world alongside him.
