   Summary

   Rui hasn't talked to his best friend for around 7 years. They're both more successful, more skilled, and more alone.

   So, when Rui gets the opportunity to reconnect, he gladly takes it — but there may be more than meets the eye on why his friend is more talented than before. Rui takes the deep dive to try and understand, but he may be going deeper than the light has reached before.

   A Tsukasa7-inspired fanfic aiming to explore the idea of what would happen if nobody ever told Tsukasa Tenma to stop.
