im even more suprised that the parents never ruined the pond after asahi came back..

they didn't know. realistically, if your daughter disappears (even right near a pond), if you can't find her body nobody would suspect that's where she went through

i said after she came back.. she came out of the pond when her mom came back home and saw her

i forgot that her mom really was Right There when she came back, but most people still wouldn't jump to supernatural causes. I think they were more excited about the fact that she was finally back and didn't really focus on How she got home
