The Royal Amagiri Twins (bnha x Amagiri!reader)

This story begins with Julis and Ayato Amagiri's kids. One having the personality of Ayato, Julis' older brother, Claudia, and Kirin(not so much) and the other having the personality of Julis', Saya, Ayato's older sister(which surprises him my a lot) and surprisingly Lester. During the Gryphs Tournament, The Amagiri twins and their team were sucked into the ground after a giant explosion in the tournament which was made by Haru-Yuudai van Amagiri's Longiflorum and his sister's Tsugomori, leaving only a fire rose made by Haru's prana. What if the world they get sucked into I full of heroes? and what if they accidentally attract attention? will they be able to find a way back? or will they want to stay in that new world forever?
