[The game board's preparation is required]

Spoiler:

In order for Maebara Keiichi to grow into a game piece that will lead everyone... this is the painful, pitiful, sad piece that he must learn first.

To learn his comrades, and to learn not to doubt.

He doesn't know yet of the weight of the words "trust your comrades".

Developing paranoia from a slight mistrust, Maebara Keiichi became trapped within Rule X.

Leaving behind a sad will, at the end of Rule X, Keiichi dies.

Although that is a very sad thing......... It's an imporant process for learning something important.

...Hey, Hanyuu.

You didn't have to apologize after all.

In the few days that he had to leave Hinamizawa for a relative's funeral.
...It's tragic that he had an outbreak during that period, but I think it was something that he needed as the first step towards learning what's important.

As the very first step of smoking out Rule X, and eventually, to defeat it.
Back when we only had this piece, we didn't even think about these kind of things though.......
