Yandere!Blue Lock x Reader
39 parts Ongoing (Y/n) lost interest in football at a young age, and for a long while opted to just watch her childhood friend play, never bothering to look much into it. After Isagi was given an opportunity to join the Blue lock program, (Y/n) was given a similar deal by Ego. Deciding to give it a shot, she joined to keep a closer eye on the players for Ego. Joining it, she didn't expect to meet someone from her past, but she also didn't intend to catch the attention of some players.
