When this reached mid storytelling, I though that tragedy would be the best option. I thought they would fight each other in the end, but this kinda fits, I didn't like etou ex machina, but that's how it went and I won't complain too much about it.
I hope the epilogue chapter ends on a happier note of him helping people, but if he also dies I won't complain, because he sustained a lot of deadly injuries.
Overall great Manga, I enjoyed it a lot, even though I didn't like tragedies.
