In the 100PC(100 Problems. Challenge) each competitor has a small watch that tells how many problems you have until you win

To get a problem, you have to make a problem and quickly run and grab your SP(Safe Person) before one of your opponent's get you

Each SP will have a device that takes one P(Problem) away from the persons PW(Problem Watch)

When you make a problem, a loud beeping sound will emit from the PW's and SP's device

On the devices and PW's the person who made the problems name will come up telling you who to look out for

At the start of the challenge two SP and a BC(Bet Collector) will be selected

The BC will go to each class and write down the names of each person in the challenge on the chalk board

After they do that, they ask if anyone is absent

If someone is, they visit the classrooms with absent people everyday until the person is there

At the end of the day the BC will check on the Bets and tally them up

Then, the next day the BC will place buckets with each competitors name in the classrooms where money will be placed

The end of the day the BC will collect the money and put the betting money together

The first person to get 100 P gets the money and is freed from their Neko form

The other competitors are in their Neko form for the rest of their life

For this particular challenge at least its a Neko form but it can be anything

This challenge will not end until someone wins

Go ahead and recommend some problems along with who will be Aizawa and Izuku's SP
