This is very bizzarre, is not to be taken seriously because she can do things like eat monster and make the sound of the sword an actual skill (Rurouni Kenshin reference???)... So the mechanics of the game are too broken to be properly explained, if she can do stuff like this just with curiosity, then that means the average players with normal skill are just too stupid and can't do more than heal and swing a sword.
I just want to see her friend's reaction when she gets back... Also, an anime was announced!! but the manga only has 3 chapters so far in raw too.
