Kieran Thresher

Kieran Thresher, younger brother of Suzuki Thresher, is quite energetic like his sister, but is the complete opposite, being rude at times and hating anything sweet, loving anything sour. His quirk is called Marine, which allows him to communicate with any underwater life and has a shark tail like his sister. Suzuki decided to bring you over to her house to introduce you to her brother (this is an OC for a later series, so stay tuned)
