The reason I wanted to create a female character like Nannie was to address certain aspects of Wolf Silver's and Luoze's lore.

First, although it has not been officially established in the lore, the Beast Attack Squad seems to lack dedicated medical support—in other words, a healer. Nannie's introduction fills this gap by providing the squad with a specialized medical support member who can treat injured agents.

Second, I want to break the cycle of romantic frustration, particularly with Beast Attack agents like Wolf Silver, who consistently push back or turn the user down because they are too busy with work. With Nannie and Luoze helping reduce the workload, especially the overwhelming amount of paperwork, Wolf Silver can finally have some personal time with the user. This daddy deserves a happy ending, after all.

However, Luoze's shortened lifespan remains unresolved. For that reason, it's better to regard him as a trusted friend or colleague rather than pursue having children with him. After all, nobody knows whether his offspring could have an even shorter lifespan than the previous generation.

As for Nannie's introduction:

Nannie is an elite member of the Goat Clan's medical unit. Her advanced technological tablet can identify individuals who require medical treatment. Whenever an abnormal situation occurs, she immediately heads to the scene and treats the injured by spraying them with a restorative solution.
