Starts out pretty good. The MC however quickly becomes quite annoying and naïve(especially for a 70 year old). This, combined with a complete lack of any motivation to do pretty much anything, really drag this comic down. The main motivation of the MC is "being normal". I mean... really? The annoying personality of the MC is occasionally also used as excuse by the author to drag out fights and/or to not kill enemies.
Beside the things mentioned above, not a bad comic. The MC significantly drags the comic down though.
A frustrating comic that could have been much better if it had a less annoying protagonist. I'd rate this a 6/10
