He did say that he did that on purpose on X lol. I actually have been enjoying Wistoria more then I have DanMachi tbh. 44 chapters so far and the only "real" harem member Will has had is Colette and she got shipped off into a completely different faction then him in the tower (she also has a lover that is after her as well, so she actually has a route after she gets rejected by Will). Other then her and MAYBE Lianna/Iris (never has been confirmed), but it's basically just a bunch of dudes simping after Will lmao. Even one of Omori's friend's pointed that out to him, that Will has a male harem instead of a female one lol (Omori agreed with that take). Elfaria and Will, the main couple, have been developed way before the story even takes place (so better then Bell and Ais imo). Eflaria literally has a 10 year head start on any girl/guy that even want's to think about going after him. So basically you can't have arguments like in DanMachi where it's "but this girl did this and that but Ais hasn't done crap for him!!" since Elfaria literally has 10 years of work put into Will before they got separated by the watcher. I like that there is not a level system that HAS to be followed to the letter like DanMachi or books just end up getting completely ruined (Volume 18). I also like that the studio doing Wistoria puts work/effort into the MC AND MH where as the studio that does DanMachi puts work/effort into the MC but then completely shits on the MH like a bunch of clowns.

Oh, and you don’t have to wait 2 years for new content in Wistoria like you do in DanMachi.😅🤣

An author reusing characters & concept from another of their work isn't something new & Omori although not subtle has been relatively tame on that aspect compared to Hiro Mashima.

As for the name, so far we have Lefiya & Filvis, a past dwarven hero named Gareth, the Elf Magia Wander sharing Riveria Family name & the head of the Light Clan (Pallum) using the surname Finn & looking like him.
