I doubt this Maya girl is any danger. Seems like she is overprotective of this Natsu person. This could be used. Say, if the MC blackmails the former by putting Natsu as the bidding stake, that Maya person would have to surrender. In fact since the weakness of Maya is Natsu, there are many ways of enslaving her. One would be to let Natsu call her saying she needs help and to her welcome would be a trap laid by the M.C., and many more. Although, I do not know what the author would choose, I doubt he'd let MC make a stupid choice knowing that the author isn't afraid to publish the content so far, ergo, this Maya person is bound to fail. As for how after how long she'd fall, how hard is it going to be to make her fall, and how deep she'd fall is something to be looked forward to.
To the fools who support Maya knowing about the dungeon and screwing the MC, know that this would mean that she's also a r*pist and she's been one longer than the MC, and you are supporting r*pe and a r*pist character (who just happens to be female and not the MC) and people (scum) like you can't tout justice. R*ping the r*pist is not the solution. If you choose this path, know that you are no better than MC and nor is the MC any worse than you are. Meaning, you are in no position, to judge the M.C. (not that you were to begin with).
To people who support Maya exposing the MC to the authorities, yes that would be quite logical, good and acceptable. However, all of us know that this manga has only had 5 chapters published. Do you really think that would happen? If you do, you're quite naive and impulsive at that.. getting enraged at fantasy ROFL 😂
And to people who support MC screwing up even more people (like me): That's Justice! Long Live Us and Let's Join The R*pe Train Family! (Was I joking? God only knows...)
