Backstory: Solaris was once the member of the Sabertooth guild until the master kicked him out for being a weakling. He was good friends with Yukino and Sting as well as Minerva but when they heard the news that Solaris was kicked out by their master they were mad with rage but swore revenge.

So after a few months wandering the streets of his hometown, he met someone in a tavern not far from his old guild. At first Solaris sees him as a traveler until the stranger explains his purpose and Solaris hesitates but eventually accepts his offer and joins his guild promising he will take care of his former master himself. The stranger known as Y/N accepted this.
