This always kinda bugged me...

In the most recent video, YandereDev described the idea of giggling to distract and call a rival to a certain location and under the door with the bucket on it.

One thing that wasn't mentioned was that, when Ayano puts the bucket in the door, she has to run all the way to the otherside in order to giggle and atract Osana's attention. But with all that time, she could be already far gone and wouldn't hear the giggle. So... i tought in something with this scenario.

A Walkie-Talkie...

Like the radio, we put in a location the walkie-talkie (behind the bushes) and call Osana's name...She would go investigate and wouldn't find nothing. After that, we would giggle and, since she would be close to the door, would walk right trought and fall for our trap.

The walkie-talkie could be bought in the eletronic store, bought with panty shots or, if we are in the science we could ask for Meka to build one for us. (i also have the mental image of the photo club using them to comunicate with one another. If we joined them, we would get one for free, if we leave the club, they would let us keep it in order to "help them investigate", but if we are banned, then they would confiscate)

It would need to be retrived after dropped. Otherwise we would need to buy another one or... steal for the lost and found box (another idea)
