"Onii-chan~ Hehe, Onii-chan~" Umaru murmured in her sleep.
Whoosh!
Suddenly, she woke up.
"Ugh, did Onii-chan go out again? I, I..." Umaru Doma jumped out of bed. "I can play games by myself again! That idiot Onii-chan!"
"Wahahaha..."
Ten minutes later.
"Why isn't Onii-chan back yet?" Umaru Doma held a game controller, but her mind was somewhere else entirely.
"That idiot Onii-chan!" Umaru Doma clutched her head, playing her game in a foul mood. "He went to see Erina, didn't he? He definitely went to see her!"
Roll around, Umaru!
And then.
"Ow, ow, ow." Umaru Doma had bumped into the corner of the table, tears welling in her eyes.
Another ten minutes later.
"Respawn!"
Now that it didn't hurt anymore, Umaru stood up.
"Onii-chan's not here, so I can spend the whole day playing games to my heart's content."
"What should I play?"
"Hmm, this one. Odyssey World."
She put in the disc and started playing.
Ten minutes later.
"This is so boring. When's Onii-chan coming back?"
"Oh, right. I'll have some snacks!"
Umaru opened the fridge. "Wahahaha, all this cola is just irresistible."
"Next... potato chips."
"Shredded squid..."
"Octopus tentacles..."
"Wahahaha, so many delicious snacks! Onii-chan's always saying this stuff isn't nutritious, but he still bought it all, didn't he?"
"Crunch, crunch." As she ate, Umaru kept glancing back. Onii-chan wasn't going to come home right now, was he?
After finishing her snacks, Umaru Doma stretched. "Onii-chan still isn't back."
"Hehe, I can keep playing games."
"But first, I should wait a bit. You can't play games without Mr. Cola, after all, even though I just drank a whole bottle..."
"Gulp, gulp."
She drank more than half the bottle in one go, her heart brimming with happiness. "Mr. Cola, you're the one who keeps me company best."
Then.
Whoosh.
Mr. Cola, her best companion, went flying into the trash can.
"Mr. Game, you're the one who'll keep me company for the rest of my life." Umaru went over and hugged the console.
The game console: "..."
The last one she'd said that to had just ended up in the trash. Honestly, it was panicking.
"Osu!"
"Hadouken."
Anyway.
When Sogo Doma came home, this was the scene he found.
He rubbed his forehead. "My foolish Imouto..."
Umaru Doma turned around stiffly, then patted the seat beside her. "Onii-chan, there's room here. Come on, come join me."
Sogo Doma: "..."
He stiffly walked over, then ruffled Umaru's hair hard as punishment. "All right, I get it."
"But it's Onii-chan's fault, isn't it?"
"What?"
"You went out without saying anything." Umaru pouted.
"Hey, hey, you were sleeping like a log."
"I wasn't..." Umaru protested. "If Onii-chan had called me, I would definitely have woken up."
Sogo Doma: "..."
Ah, probably.
"Anyway, it's all Onii-chan's fault!"
Sogo Doma: "Fine, fine. You're right about everything."
"So Onii-chan owes me one favor?"
"What?"
"Hmm?" Umaru widened her eyes, looking ready to burst into tears if he refused.
Sogo Doma: "..."
"Okay, okay, you idiot."
"Onii-chan's the idiot!"
Sogo Doma: "..."
That's right. He was an idiot from the start, an idiot who existed only to protect her!
"Onii-chan, you're smiling so creepily," Umaru Doma said, shuddering.
"Idiot!" Sogo Doma laughed.
Umaru wasn't about to back down. She pulled faces at him. "Onii-chan's the idiot, idiot, idiot..."
Sogo Doma: "..."
"Fine, I'm an idiot."
Umaru: "?"
"If Onii-chan's an idiot, then doesn't that make his Idiot Little Sister an idiot too?"
"I'm not!"
Looking at the angry Umaru, Sogo Doma stepped forward and hugged her. "All right, then. I'll be the only idiot."
For some reason, Umaru's face turned bright red. "I'm not..."
"Hmm?" Sogo Doma looked puzzled.
"Onii-chan isn't an idiot!"
"Huh?" Sogo Doma stared at the fuming Umaru, stunned.
"Even if you are an idiot, you're still my favorite Onii-chan!"
Sogo Doma: "..."
After a moment of silence, he smiled and spoke.
"And you're my favorite Imouto, too!"
"Onii-chan!"
"Want to play a game?"
"Yeah!"
"Onii-chan, your character died again."
"I know, I know."
"Maybe Onii-chan really is an idiot."
Sogo Doma: "Idiot Little Sister."
"Hey, what should we have for dinner?"
Umaru covered her mouth. "Well, how about sukiyaki?"
Are you trying to work me to death so you can inherit my TL? Sogo Doma gave her a death glare.
After a while.
"Fine, fine."
Umaru's Diary.
"The sukiyaki was delicious, and Onii-chan's expression was so funny. But of course, games are the most fun! Next time, I'll make Onii-chan buy the best game ever..."
The next day.
A new game sat beside Umaru's bed.
Sogo Doma lay sprawled on the floor... I really am an idiot, aren't I?
The little dumpling: "Wahahaha, a new game appeared out of nowhere! This is amazing! Next time, I'll get Onii-chan to play with me."
