Read this from the post to the repost! This is in a weird order.
(Again, TW just in case)
Unfortunately, that planet is next on Efril's list of planets to destroy. Qwertyx befrends a few of the planet's natives, and goes on this cool quest to save the planet. The more notable ones are Victus, who was more of a rival than a friend, and Kayle, who he slowly falls in love with. When they are nearing the most difficult part, Kayle confesses that they reciprocate feelings. This would be short lived, however, as not a day later, Yui shows up while Kayle and Qwertyx are alone. Yui grabs Kayle and just explodes them in front of Qwertyx, who is now horribly traumatized. He runs back to the other people, and tries to get them to help. Yui tries to pull him through a portal, but Victus refuses to help. Yui beats Qwertyx's ass and dumps him elsewhere on the planet. He crashes with his only remaining friend for about a month, before moving out. While this was happening, Victus, accompanied by Qwertyx's former friends, saves the planet. Every day, on the same day that Kayle died, everyone celebrates, leading him to really dislike the day. Around ten years and multiple depressive episodes go by, and Qwertyx is now on a new adventure, and still depressed.
(TW, had to cut will add the rest in repost)
Qwertyx was a happy kid living with his well off family on another planet. That is, until a being known as Efril and its family of horrors decide to destroy said planet. Qwertyx escapes through one of their portals, and is left in the capitol of the universe alone. He is basically a street rat for a few years before Efril locates him. It has some of its so-called family retrieve Qwertyx, as it sees an opportunity to exploit his powers. He's dragged off of the streets and into a life of luxury, which he hates. This wonderful, lovely, absurdly rich lifestyle was messed up by quite a few things. Qwertyx had an adoptive mother who would do nothing but berate him and yell at him all the time, his sister, Yui, was manipulative and terrorized him, and he had to visit Efril for any important family business. (He remembers Efril, so he really doesn't like it.) When he is older Qwertyx is forced to start training for his family's guild of assasins. He decides to expose the entire thing. In anger, his sister banishes him to a far away planet and stripping him of most of his powers.
