Blue Lock Isekai: Reincarnated as the NPC Side-Character in a Dense MC's life

Isagi Yoichi never thought he'd end up stuck as an NPC side character in the world's worst isekai anime. One moment, he was in Blue Lock. The next, he woke up in some random medieval cottage straight out of a discount history book. His "mother" told him to hurry to the prestigious Academy of Lightbringers and Eternal Hope™.

That's where he met him: Tanaka Taro.
A boy with the haircut of a coconut and a personality that made unseasoned boiled chicken seem like fine dining.

Now Isagi's forced to watch this bland protagonist stumble his way through every cliché imaginable: motivational speeches that somehow defeat princes, a harem of catgirls tripping into his arms, and villains who only exist to lose dramatically.

Alongside confused ex-princes Reo and Nagi, a pissed rival Rin and also Kaiser, Isagi must endure the ultimate nightmare.

His greatest rival isn't Kaiser nor Rin. It's the plot holes.
