Pathfinder: Saga of Fate/Hiroto Kituhara

Hiroto Kituhara is a kitsune summoner who uses his eidolon, a giant golden frilled lizard named Solavoto, as well as temporary summons, to assist him in battle. He is capable of changing his appearance into a rather handsome human.

Backstory
Hiroto was born in Tian-Xia, a continent far to the east of the Inner Sea, to parents who were part of a group of mages who would travel across Tian-Xia closing portals to other dimensions and stopping rituals that would summon evil creatures from other planes. When Hiroto was just a toddler, the group decided to extend their work to the west in the continent of Avistan in the Inner Sea region.

Unfortunately, the Kitsune summoners had their work cut out for them, as they had started working during the Inner Sea War, in which two of the factions frequently used portals to Hell and the Abyss to bolster their ranks. After being driven out of the territories of Solomon and his demons, the summoning group went to Cheliax to try to stop Judas's rituals.

This did not go very well for them.

Several members of the summoning group were killed by devils, and the survivors, Hiroto included, went into hiding in the mountains, disguised as humans.

When Hiroto grew older, he began training himself in halting the summoning of evil creatures as well as summoning creatures of his own. At one point in his training, his eidolon chose him. The eidolon has stayed with him to the present day, and is a creature from an unknown plane that looks like a giant golden frilled lizard. The creature called himself Solavoto, and saw Hiroto as worthy to serve.

Hiroto left his settlement to travel with his eidolon at age 23. During the time the Kitsune were in hiding, Cheliax had fallen into anarchy and controlled by a gang known as the Iron Cog shortly after. Devil summoning rituals occurred very rarely, if at all. Instead of continuing the mission of his parents' summoning group, Hiroto turned to fighting injustices that occurred in Cheliax.

After 2 years of fighting petty crimes, Hiroto's travels took him to the port city of Corentyn. There, he witnessed an unfair arena battle between a vanara brawler named Lu Kong and three unarmed Iron Cog members. This was overseen by Solangus, one of the Iron Cog's second in commands. Hiroto decided to put a stop to this, and sent Solavoto into the arena to interfere. Another audience member, a witch named Hanji, seemed to have the same idea, and had used magic of her own to interfere. Lu Kong survived the battle, but Solangus managed to escape. The witch Hanji offered Lu Kong, Hiroto, and a mysterious assassin named Raalnorg that had attempted to kill Solangus to team up and stop Solangus once and for all. All three accepted the offer.
