I think they already have expertise fighting with mana, actually.. I think our main lead might be the weakest one if she's not fighting against cannon fodder.. which is kind of disappointing when they spent so much time hyping her abilities up. I mean, shes still a gifted learner but if her friend (if thats who he really is) can create shock waves like that when he's been in that world the same amount of time, she's kind of had a slow start... he was probably filled in about mana a lot sooner
I'm guessing the jewels are probably only developed after years of saving up mana in the chest area. and signify a certain level of status as a fighter. tho this is just my guess.
I think her former teammate been reincarnated from the get go. Kasia took a while because she was in hell. She was merely given a 2nd chance last minute. Her soul suffered for a long time... I guess the author did point out that FL killed innocent lives...what we know so far from the former teammate is he betrayed and killed Kasia, but the author did not show if his sin is equivalent to Kasia's... And looking at his rank and knowledge about their current world... He must been reincarnated since birth
I think your right about that. some minor spoilers but I think she calls his name in the next chapter and he doesnt react to SEEING her, let alone her calling him by some other name (like at all..)
They have always been skirting around the topic so as to keep the illusion the MC was the most OP of the bunch, but now that we see our protagonists limits when fighting and what [Mana] can do in combat, I'm curious how she would fair against someone like Mikail or the Prince for instance? They have jewels in their chests. surely they aren't just a neat accessory choice? we have yet to see them fight seriously..
