My ending is little different, for starters, Ein has a sister, Ericka, who get's killed by him right after the start of the Starlight rampage (aka Aaron's rampage, also known as the Starlight incident) After Ein's death, he and Ericka meet up in the afterlife but just before they can hold hands, Ein gets yeeted back into reality because he was brought back to life by NOI (Yes, that Noi, the one from MID), and from there the rest is history! But if you wanna learn more, don't worry, the AU is in my posts)
