I think this is clearly going the harem route. If not then, then Maura being the first girl that got the most attention throughout should be the winner.
I'm unsure how to feel about this series... it's okay, but it feels like the MC is someone who just isekai'd into their world with an OP cheat and zero clue.
You're thinking of Eminence in the Shadows. Actual isekai protag who is doing this stupid let's-pretend chuunibyou fantasy even though he's in another world and that should be enough chuuni, but nnooooooo, that not chuuni enough for this guy...
....but then it actually turns out his let's-pretend-play is actualy fucking real, down to the last detail, and he spends waaaaaaaayyyyyyyy too long thinking that everyone is just playing along with him, because that shit can't actually be real, right?
Right.
its time for gaile to kill a dragon and an undead legion of adventurers and then be shocked when he finds out that they are actually a legendary dragon and an undead legion of s ranked adventurers
Even better. S-rank adventurer undeads and a legendary dragon will provide better materials for cursed tools.
They won't be Demon King Series, but it'll do for an appetizer.
Who knows? Maybe Death will show up from all the dead division members. Gaile could use a second talking skull for the shop
Narrative Imperative requires they will run into the dragon, of course. That flag has been raised so high you can barely see it from the ground...
I'm quite curious to find out what insane cursed item(s) will be used to defeat it. That's half the fun on this Manga.
