Unforgivable. Definitely unforgivable. Turning the resentment he
held for those two into strength, he moved his right arm. Inside the
scabbard, the blade slid through bit by bit. The sacred letters in his
sight steadily enlarged in proportion to that, with their rotation rate
speeding up as well.

“N-Noooo——! Senpai——!!”

Tiezé shouted-

“U... oooaaaa———!!”

And Eugeo screamed as well; that was when it happened.

With explosions of silver light at his right eye, the eyeball itself
popped out from inside with a splattering sensation.

His vision degenerated to half of what it had been, but Eugeo still
ignored it and savagely slid the Blue Rose Sword out of its scabbard.
Before it was completely drawn, the blade already carried a blue
radiance.
