This is not a copy of the HK-416

The STM-416 is a Russian rifle, inspired by the German HK-416 and the American SAI GRY AR-15.

STM-416 loves her "cousin" HK-416. She tries to imitate her but doesn’t fully copy her.
STM is kind and innocent. She always helps others and puts their problems above her own, which sometimes ends badly for her. She loves cats and is afraid of street dogs.

In conversations, STM is very shy, sometimes she can’t even get her words out. However, when the T-Dolls got to know her better, she became more confident in talking. As for the Commander, she tries to avoid him because she’s afraid of him and sees him just as a mean person.
