Truly one of the delinquents of all time, going limp from one kiss. Very adorable.
Clearly she's innocent and just fronting. Satou mentioned that the industrial department at her school has a bad reputation. Maybe she got roped into being a delinquent against her will. Maybe she did it to fit in. Or maybe she was a loner in middle school and underwent a transformation for her high school debut. It's yet to be seen, but I fully expect that to get tackled in this arc. Just like how Koharu's arc was about finding the courage and confidence to battle her oppressor and play baseball again, Delinquent-chan's arc, I assume, will revolve around Satou helping her deal with whatever made her a delinquent in the first place
Thanks for the translation!
