Miura the fucking MVP.
Imo it is already a tragedy for Lucas. He wanted to be free from all the killing and his life being directed by someone else, and this chapter he concluded that the only way for him to be free is more slaughters.
* Arc pacing is great, we don't meander around with one problem for more than 10 chapters
* We get to see the actual revenge
* You (and us) enjoy watching the MC suffer
We have timeskip chapter right after he lost or at least badly wounded, and before that a chapter of his backstory.
Odds are that he survive somehow, though I welcome to be wrong this time.
Thanks for the chapter
Only stepping stone? Quite the unusual reaction when the apprentice overtake the mentor. Maybe that's why his smile and possibly mannerism changed?
Think we'll see him again in future arc.
