Well, perhaps it could be about a neko girl who starts leading a very lazy lifestyle. She eats a lot of junk food and doesn't exercise. As a result, she begins to gain weight. Maybe she then has to deal with things like fitting into her old clothes or being teased by others, but eventually learns to embrace herself and make positive changes.
There could be her friends. For example, a more health - conscious friend who tries to encourage her to change her slobbish ways. Or a friend who is also a bit of a foodie and sometimes enables her bad eating habits.
One reason is the lack of physical activity. Gaming often involves sitting for long periods. Another is poor diet choices. She might choose easy - to - eat junk food while gaming.
A gamer girl who is an extreme slob might gain weight due to her sedentary lifestyle. She could be so engrossed in gaming that she forgets to take care of herself. For example, she might constantly snack on junk food while gaming and rarely exercise. This lack of physical activity combined with a poor diet would lead to gradual weight gain over time.
Another theme is the journey of change. They usually have to overcome their bad habits. This could involve things like learning self - control and starting to exercise. It's a process of transformation from being a slob to a more healthy and confident individual.
Well, it could be about a character in High School DxD who starts overeating due to some emotional turmoil, like being bullied or stressed about schoolwork. As they keep indulging in junk food, they gradually gain weight and become a slob. Their appearance and new lifestyle might cause changes in their relationships, for example, some friends might distance themselves while others might try to help them get back on track.
One anime that might have elements of this is 'Kaguya -sama: Love is War'. In some episodes, there are comical situations where characters might overeat in a slobbish way which could potentially lead to some weight gain implications. But it's not the main focus of the show.
Rias could also be the main character in such a story. Imagine if she goes through some sort of magical accident that makes her gain weight. As a high - status devil, this would be a huge blow to her self - image. She might become a slob as she struggles to come to terms with her new body, and it could be interesting to see how she tries to regain her confidence and status within the school and the devil society.
Once there was a girl named Lily. She used to be very skinny. But then she started a new job at a bakery. She was surrounded by delicious cakes and pastries all day. Unable to resist the temptation, she would have a slice of cake or a muffin every day. Over time, she gradually gained weight. But instead of being sad, she embraced her new body shape as she realized it was a sign of her enjoying life.
One reason could be overeating due to emotional issues. For example, if she has problems at home or with friends, she might turn to food for comfort. Another reason could be a lack of physical activity. Maybe she's too busy being mean and not focusing on taking care of her body. Also, it could be related to hormonal changes, which can sometimes cause unexpected weight gain.
