So in My Hero Academia, Deku has this little notebook where he writes down information on the superpowers of the people around him for studying purposes. The kanji floating around him translate to something like “mutter” and crop up while he mutters to himself about what he’s writing/reading. My original plan was to have him scribbling down notes on Kirishima’s hardening ability, but then I realized that I’d accidentally drawn him reading instead of writing… I also didn’t have any idea what he’d actually be saying, so I decided to just have him reading the notebook instead. Probably he already has notes on Krisihima’s quirk and is just reviewing while studying the effect with his feet.
