Finally, I was starting to experience withdrawals from generic isekai. Looking forward to when it timeskips to his teen years and when he gets his equally generic harem. Hopefully the baby arc ends soon, it's a bit too unique for my tastes.
Sure thay can, you just have to make vibrations to make sound. you know like how a normal speaker work.
getting anything other then just some random sound would be hard tho
To be honest, i wish isekai's "originality" would go beyond weirder and weirder starting cheats. Like, I don't know, character personality or something?
