What role can primary school students play as the fifth personality of COS?

I think Eli is very good. He was all wrapped up and wearing an eye patch. Even if his face value is not high, the impact is not that great. Girls can also be cos prophets, primary school students, hypoplasia, Eli is still wearing robes, and kanb is more gender-conscious. Eli still wears a hood, so it doesn't matter if he doesn't buy a wig.
