Review Detail of Drimy in Naruto : The Demon Swordsman

Good read, only issue I have with it is that the MC is supposed to be a 45 year old soldier. He doesn't act like one at all. Then they go on to explain that he lacks battle experience when he has been in the army for years.... Another minor thing is the last wish still bugs me. Him wanting 2 contract scrolls seems so pointless. Like what even is the use of that? Are the beasts he eventually contracts going to suddenly gain intelligence??? Cause if I'm correct, only the summoning clans have intelligence. So, these contracts just seem so pointless and a downgrade from just getting a different wish?????
