I can't remember if they have or not and skimming the first couple chapters turned up nothing, but given that Satsuki is stated to be a high school student in the description, that puts her (and Miyu) at between 15 and 18; unless her parents had her real young (or there was just a solid age gap between them and Renji), that would probably put MC at late-30s, early-40s.Did it say how old the uncle was?
Of course, this works fine until it doesn't and then you die. No wonder his generation had such high fatality rates. Naturally, anyone good enough to have made it through is stronger than the modern dungeon explorers, but I don't know that I'd call it a better strategy.Fair enough. If it has a head cut it off. If there are things blocking the head, break it. If it bleeds, we can kill it. The difference in power is all it takes.
Is that you, Emiya?"My strategy? If you kill it, it dies"
