Sonic The YANDERE!!

Things turn a bit surprising when Sonic felt happy and surprised to know that Knuckles confessed his feelings for him. Things were going their way until two certain ex-girlfriends attempted to sexually harass or rape him and a few certain men kidnap the echidna in four alternative times and that took a deadly turn and they have made a grave mistake that was when Sonic who was the sweet and innocent Sense-Chan turned into a deadly and dangerous yandere for his senpai.
