I love that grampa-knght got some desserved badass scene. Best even is that he flexed without even trying. Going for the kill in an emotionnal level. Showing such difference in strenght that he allow the other to flee without losing face.
People are saying this arc is long even though it started like 7-10 chapters ago(?). It's because it's a monthly series, that's why it feels long. Binge read it and you'd think it's short or relatively average in length.
