The otaku was sent to a parallel world by his grandfather, where technology is advanced but entertainment is backward, so...
Become handsome? This is the first condition; memory? It definitely needs to be strengthened, photographic memory is good; then there is proficiency in musical instruments, and then there is top musical talent.
Do you think I can only sing? I can also write screenplays, but as for acting, I don't need to do it. It's too tiring. I can just open a company and find others to act.
All in all, this is an otaku's peak journey.
