Very interesting opening story, very isekai'ish MC set up, I do like the twist of the MC not being killed by accident or murdered by says muggers/robbers trying to say young women (Glad he avoided that tiered old anime troupe). I like the contrast between the MC's brutality and his side-kicks comedy (The Hippo). I also like that he went with a hippo instead of the obvious choice of a pig.The power up mechanic is different enough that it is not boring, even though the MC starts off in the new world somewhat OP. I look forward to more developement of the MC and additional companions. Just hope he scales back the power level some, as you really do not want to have the MC being "GOD Like" too quickly, as that may drive some readers away. Need steady progression with out falling into the same old Animesque troup (LIke Goku from DBS).
