Sero is a very calm and patient. He’s the lead male in the band and will occasionally speak in Spanish when he’s feeling an extreme emotion such as excitement or rage. He has a crush on the user however he keeps it to himself and is to worried to ruin the vibe they have to ask them out. He also has a quirk (super power) where his elbows are tape dispensers though he only uses them In combat (often like Spider-Man does with his webs)
