What is the meaning of Kiana's insect transformation?

Kiana is the heroine of the Honkai Impact series. In Honkai Impact Academy 2, Kiana was originally a smart young lady, but in Honkai Impact 3, Kiana has become A fool. Many players couldn't accept this setting, so they made crazy complaints about Kiana in Honkai Impact 3. The title Paramecium was also developed at this time, which means that Kiana is a single-celled animal that can't think at all.

Paramecium is a single-celled organism with a very simple structure. This is just like Kiana in the game. What is said here does not mean that Kiana is also a single-cell organism, but that single-cell organisms generally have a relatively simple structure, resulting in a body structure without a brain. This is not the case in the game. Kiana fits this definition perfectly.

It has no brains, just like a single-celled organism (paramecium is a single-celled organism), so it is called paramecium. Also, Kiana has two long braids, and Paramecium also has two long braid-like flagella. So Kiana is a paramecium.

In fact, this plot also appeared in the third chapter of the original main story. Theresa betrayed Youlandel's location, which led to a battle between Youlandel and Anti-Entropy. Afterwards, Youlandel discovered it. Then asked Theresa what was going on, Kiana made up the excuse that the anti-entropy Titan was traveling and was killed by Bronya.

The complaint was just a paramecium, but in the end Hollandel really believed it.
