Starting in High & Low

An otherworldly soul arrives in the world of High & Low and becomes the fourth son of the Amamiya family. For reasons unknown, he awakens as a low-temperature artist, a being shaped by the mind. He kills a transmigrator, obtains coordinates to the multiverse through a group chat, and travels through different worlds to experience life and stir up trouble.

What changes will this low-temperature artist bring to the multiverse, when he can ignore the light-speed barrier and the dark forest, leap through space, cross dimensions freely, know and do everything, and live without fear of running out of resources?
