It's so cute story and i love this older brother with a language system and baby brother a regressor i think or may have a power to see futures cuz if you remember the drawing he did that he was sliding and his brother waiting for him at the end of the slide as if he already know it or maybe he experienced it before too..... I don't know hahaha
They're not just a friends for him but also a family they grow up together since middle school or high school until they graduate then live together after the accident about their parents, they only have each other to lean on so them dying for the sake of his life is basically a big trauma for him too i understand if he wants to die to meet them again he don't want to be alone. So this chapter is were as his friends saying that his going to be alright and happy are the closures that he needed the most, he tell them about him using his piwer to them just to survived is also a good thing to lessen his burden in his heart and his friends saying it's okay if it's going help him survive is a signal that he doesn't need to about this and move on and be happy fir there sakes also so this is so touching for real even in the afterlife they still cared about him. (so sorry if my English is not good haha )










I think the old man is helping him? Because of his master and that guy behind are enemies?
