Kamijou ended up having his head bitten magnificently and he unlocked the door of his dorm room while rubbing the back of his head.
"Nn…It's a bit chilly in here."
He turned on the lights in the room, grabbed the remote to the air conditioner, and turned it on. Index ran over to the TV and sat down while Kamijou headed for the unit bath and used the panel next to the tub to turn on the automatic hot water mode. Today was the day to wash the cat, so he prepared a wash basin.
(It's nice not having to make dinner or wash the dishes…)
Kamijou raised his arms to stretch and left the bathroom. He was full, so all that was left was to soak in the tub, brush his teeth, and go to bed. It was just too nice. It tempted his heart towards eating out more often, but, according to the account data on the finance app on his phone, he'd have nothing to eat but water and salt for the second half of the month if he did that.
He had started to wonder how much the nabe had set him back and had started to operate his phone with his thumb when the phone suddenly started ringing.
When he changed the mode, he saw Misaka Mikoto's number on the screen.
Kamijou hit the talk button.
"??? Do you need something, Misaka?"
"When are you going to reply to that email!?"
(Email?) Kamijou tilted his head to the side in confusion.
"Hmm, I can't quite remember what you're talking about…"
"!? How careless can you-…"
Mikoto was yelling something, but it sounded like her voice was becoming more distant and then the call suddenly ended. Kamijou looked at his phone's screen, but he still had a strong signal.
(…Misaka must have lost her signal.)
Kamijou dismissed it and went back to the finance app.
He plopped down in front of the glass table in the center of the room.
"Index, you shouldn't sit so close to the TV."
"B-but the 'Thinking Power-Increasing SF Health Quiz' is reaching its climax!!"
"…There have been a lot of that kind of science and brain related quizzes lately, haven't there?"
(Well, some of the stuff comes up in Academy City classes.)
Kamijou didn't really care about the quiz show, so he looked over at the cat on its back basking in the heat of the air conditioner.
"Hm. If you're not doing anything, I guess I'll wash you first."
He took out a bottle of animal shampoo and a mini-sponge shaped like a cat's head, but the cat must have sensed something because it ran to hide in the kitchen as if to say, "I hate water and bubbles!!". It was probably trembling in fear while hiding between the fridge and cupboard.
Now it was covered in dust so Kamijou was going to have to wash it even harder.
But then…
"Hm?"
His phone started vibrating.
It wasn't from Mikoto this time.
The small screen showed the number that had been newly recorded just a little earlier.
