[Crossover] The Fat Man Saves the World

The girl is a chubby little thing. Before she transmigrated, she was a chubby little thing. After she transmigrated, she was still a chubby little thing. As a chubby little thing, she just has to be heavy! Steady! Because if she accidentally gets lighter and thinner, the whole world will be in for it. [Anyway, the task of keeping the world steady is now in your hands!] “Give me a fulcrum, and I can lift the whole Earth.” “Face the facts: chubby girl = the world.” “I am Saionji Sekai. I am the world.” A few things to note before reading: 1. The pairing in this story is set: one-on-one romance. No changes to the pairing will be accepted. 2. Most important! The heroine's characterization will not change! Read with care! If you can't get used to the setup, please click the X in the upper-right corner. 3. It's fine, really. The silly author considers herself to have normal values. At most, I just tend to lose things now and then. 4. Although people rarely scrape the rankings these days, I'll still put up a “No ranking scraping” notice. 5. There may be bugs, out-of-character moments, and logical inconsistencies. Please point them out, and the silly author will make changes as appropriate, based on the setup and how the story develops. 6. Finally, the heroine's name is a joke. This Saionji Sekai is not that Saionji Sekai. That's all. Here's a preview of some upcoming stories.
