I rolled my eyes seeing another villain isekai so soon, but I opened it up and... OMG this is so funny! I am really looking forward to seeing more of this, because I legit laughed out loud a lot.
man, it sure is rare to see someone got reborn as villain but actually want to became stronger to fight along side the protagonist, not just the usual "i just became OP to avoid death flag and live a slow-life"
