A professional gamer dies unexpectedly during an E-Sports tournament and is sent to Valhalla, a heaven reserved for only the greatest of warriors.

High society CEO Big BOSS Lu expresses that he’s felt stifled recently. Ever since a woof style creature intruded upon his home, his life has become a complete mess.

Big BOSS Lu lowers his head and makes eye contact for three seconds : “…. Give give give! Whatever you want, I will give it to you!”
