Something like Bam from Tower Of God(TOG)? He can copy things really easily if he sees or is damaged by it once. I guess it could be fast learner regarding things related to him becoming a hero(cause he stupid and unmotivated in all other areas of life XD). Good chapter overall looking forward to the next.

Okay so Krino best boi(sword?). What you did to Tif in you know what chapter absolutely unforgivable! Enjoying the world so far can't wait to get more info on the voids.
