I didnt give a fuck about that hero wannabe and dont care about his generic hero harem. However one thing is clear... 1 year later since the summoning, they have failed.
I gonna guess here.... but most likely this new girl was sent to gain the aid of the "last" isekia guy, who they only just realized he had been forgotten about (and left behind) all this time ? Their last hope ? Well it seems the MC is smart enough to be already onto her, hes already detected somethings off about her. Lets see where this goes :3
