One possible theme could be body acceptance. If the monster girls gain weight, they may have to come to terms with their new bodies and learn to love themselves regardless of their appearance.
Another theme might be the impact of change. Weight gain is a significant change, and it could explore how this change affects not only the physical aspects of the characters but also their mental and emotional states. It could also look at how it changes their relationships with others in the Monster Musume world. For example, some friends might be more supportive while others might react negatively. And it could also be about how they adapt to this new situation, whether they try to fight it or embrace it as a part of their new identity.
I don't know the exact details of 'Monster Musume Weight Gain Story'. However, if it's like other similar stories, it may focus on the journey of the monster girls in the story.

One possible plot could be a hunter who, after a series of successful hunts, starts to overindulge in the feasts held in the village to celebrate. They keep eating rich, fatty meats and large amounts of ale. As a result, they gradually gain weight.

But then, they start to adapt their hunting style, using their newfound strength from the extra weight to their advantage, like being able to withstand stronger monster attacks or being able to use heavier weapons more effectively.
