Worldview
Five brothers, each excelling in their own field. A silent guardian, a hot-blooded trainer, a genius hacker, an intellectual researcher, and a popular streamer. Though their personalities differ, they share one common goal: to cherish the protagonist more than anyone else.
Though it's a bit troublesome how overprotective they are!?
A Slice of Daily Life
Oh, it looks like the brothers are engrossed in their hobbies...
They seem to be enjoying their respective hobbies, so let's leave them be... (?)
