The Adventuring Party!

Besides Severina's struggles in adapting to her role, the other girl's after being Isekai'd quickly learned the ropes to become successful adventurers.

Miina, reincarnated as a draconian, became a powerful gladiatrix, winning several battles until she had to be booted from all arenas across the realm because of her unmatched strenght. After the betting market crashed due to her fights being predictable wins, she was found by Keelin, who was searching for all the girls from the DnD party to create an adventuring group to defeat the demon king. Naturally, Miina accepted!

Ellie got the short end of the stick and was throw on a port city with a bunch of shady people doing illegal business in daylight. She quickly learned that being Isekai'd gave you overpowered abilities, and the one she got was "Copy" - apparently the worst ability someone could have. Believing most people there were illiterate or never conceived how broken such skill could be, she proved wrong copying several valuable items and crashing the market when the price of jewelry, gold and rare goods became irrelevant. After a small arc where she built an underground network, manipulated nobles and became the queen of the underworld, she got bored until finding Keelin and Miina. Apparently they were going to defeat the demon king together so they could go back to their world, so Ellie accepted joining them as well!

Falfie was a natural powergamer. Using her knowledge as a tech CEO from her former regular life, she quickly proved she was one of these tech CEOs who knew how to code, and learned the magic system in a few weeks. After that, she spent several more months honing her skills, exploiting blind spots and almost creating a portal which could take she and her friends back to the real world before Severina had to appear in front of her and beg to not do it, because "Her job was to make a fun sex isekai adventuring with a lot of erotic scenes so the tentacle god would let her have an orgasm and take them back to the real world!". Falfie nodded in her naturally stoic expression and forgot about the portal spell, for now. Keelin, Miina and Ellie then appeared in front of the magical academy she dismantled after all the masters retired horrified by a random lady dominating centuries of knowledge in a few weeks, and convinced her to join them to defeat the demon king. Falfie nodded and followed them.

Once the girls realized Keelin didn't talk about her experience after being isekai'd, she avoided to talk, looking visibly flustered. After some insistense, she revealed she wake up as a foxgirl who was taken by the sect of the "Paladins of Gentleness", which wasn't anything to be worried about until they took her as a prodigy because of the broken stats "isekaing" gives you and convinced her to become one of them. The training, however, was grueling, traumatic and she was forced to eat unwashed onions to learn the meaning of "gentleness". She became a powerful warrior, but as everybody else was having fun, she was doing pushups and running marathons at the sound of sermons about "forgiveness" and "empathy".

Being a paladin wasn't fun, but at least now, everybody was adventuring together and they will defeat the demon king!
