Souji thought he might have still been sleepy from the train ride. The girl he saw behind his uncle was rather fat, far larger than the tiny girl in the photo. Her face was quite spherical and nearing a double chin while her bulging tummy stretched out her dress close to the seams. Nervous as she looked, she gave a small wave to her cousin. Even her hand looked to be coated in a layer of chubbiness.
"H-Hello, Souji-kun." Souji smiled and waved back, saying it was nice to meet her. He then heard a low growl from Nanako, who blushed and patted her stomach. "Sorry, I'm a little hungry."
"There should be some snacks around here." Ryotaro gave his daughter a few yen. "Hurry back, okay?" Nanako nodded and waddled off to fill her tummy, bouncing all over which each step. Dojima then turned to his nephew. "I know you have questions about Nanako's weight," he said as if he read Souji's mind. "I'm not really sure what happened myself, but Nanako developed a much bigger appetite not too long ago. She'd always feel hungry even after stuffing herself full at dinner. I wasn't really sure what else to do, but since she usually cooks anyway, I let her feed herself until she started growing."
Souji then asks if Nanako was in any danger. "Her doctor's appointments never showed anything wrong. In any case, it's made her happier since her mom passed. She has enough to deal with since I'm always busy and she does so much around the house. Figured if she wants to spoil herself a little and fatten up, I won't stop her. Besides, I don't think she's that unusual these days. Take a look around." It was then that Souji finally noticed what should've been obvious.
After Nanako got her snacks, Souji took a tour around Inaba and found something he didn't expect. There were an exceedingly high number of women around town who were overweight or downright fat. Primarily those who were around 35-40 or younger were all about double the weight they should've been. Any one of them who wasn't wearing a dress had her belly exposed. Schoolgirls some years below Souji's age dug into large steaks from Souzai Daigaku, popping buttons on their shirts. A couple of housewives stood around talking and laughing at some of the latest gossip. Their bellies quivered and fell even lower on their skirts. A little girl around Nanako's age ran as fast as she could to chase some boys around Tatsuhime Shrine. She didn't seem to mind that her skirt rode up enough to expose her panties as she ran. Not to mention she was somewhat winded, but still had a decent amount of energy. Souji had no idea what to make of it, especially when trying to remember what the man with the long nose said.
"Some of your Social Links are on the verge of growing." Is this what Igor meant? Were these women all getting fatter because of his choices? Souji didn't even remember who these people were, but he felt some kind of concern when he wondered about Nanako's health. Were these women going to be okay, too? Even stranger was that it may not have been limited to just Inaba. The girl in the soda commercial, the one in the swimsuit. She was much larger than he thought. She had to weigh about 100 kg and there she was, saying she's not worrying about diets anymore. She embraces herself and drinks the soda to prove it. Was that what caused this wave of weight gain? Did it spread outside of his awareness? His mind continued to race as he returned to the Dojimas.
At the car, Souji thought he saw a girl in white and red by the gas station and swore he heard her muttering "Who am I?" She seemed to disappear as soon as Souji saw her. Nanako already started on a candy bar as Souji entered the car.
"Did you see her, too?" Nanako asked her cousin. He shrugged as he didn't know what he saw. He didn't even know if she was big like the rest of Inaba. "I wonder what she was doing?" Nanako went back to her candy and continued eating as the trio entered the house. When she finished, she gave her belly a few gentle pats. "That was delicious. Well, time for dinner." Souji had to wonder if Nanako really had that much room so soon after eating. Her dress started riding higher as she started. Souji tried averting his eyes but caught a glimpse of white underwear as Nanako reached for a high can. His uncle had gone into the bathroom, so he walked into the kitchen to help his cousin. "It's okay, I-I can handle it," she insisted. Nanako had gotten used to doing things herself and Souji was still technically a stranger in her house. It'd take some time for them both to adjust to this new situation.
