Bgbl has them all, they are all original protagonists × original characters. Awaiting editing, but there are many critical comments, so read with caution. Direct links are recommended, and those not recommended are placed in the comment area.
I read the story about Ito-sensei, but I felt that the character was a bit flat, even if it was a side story, the second episode was pretty good. The overall feeling is that the Caesar line is better. The above is only based on my perspective. If you like to read Otome novels with many single arrows + career lines, this is quite good. Although the career lines are not very rigorous, the complex relationships between stars, fans, clubs, and regions are well written.
I won't comment on whether the characters are OOC without reading Blue Lock, but the other parts are really thin. TT's writing style is very graphic, the foreshadowing and turning points are very well organized (at least for a fan), and the degree of completion is also very high. You can feel that the author has carefully created the heroine, and is very ambitious and self-centered. He has extracted the most attractive aspects of Blue Lock's idea and established it very well. The setting is talented, so it's a cool story. I don't usually like cool stories, but this one is really well-written. . TT
