Because that's like the first instinct isekai protags have. Despite EVERYTHING that screams "I'm from another world" lets try and hide the fact that I'm from another world.The adult look is the illusion... welp bracing for the gilf peeps.
Also does anyone remember why MC is hiding the gate from Aina?
probablyI bet grandpa looked like a japanese Mel Gibson in his youth.
No way man. . . . .So......... the grandma will enter the harem???????
Don't think so too, i feel their familial love being very strong in the LN.Does it say she does in the LN? Because somehow I doubt it.
I got theory so the reason granny is perpetually young is because of that clock thingy she has around her neck and that thingy is actually some type curse as she is a witch not a magician, i befor knowing she was witch i thought that clock thing made time for her body to go back but no, thatthing only makes time stop , for her to have visually aged she used magic.So his granny is kinda immortal.
That is interesting.
