Tokyo: After years of stagnation, the heiress of the yakuza arrives.

Tokyo, Rat District, Kuroba Shidoka.

Unlike his usual anxious return home, today Shido Kuroba walked with his head held high, not for any other reason than that some damned blonde punk girl had been punished by justice!

You wretched bastard! You're only bullying me because your Uncle Kuroba is injured and his fighting power is lowered. Otherwise, I'd show you why flowers are so red!

I regret being born!

Now is... time for fantasy!

What was he babbling about? Anyway, he won in the end. Haven't you heard the saying, "History is written by the last victor"?

As luck would have it, he was the ultimate victor!

Wuhu!

Go home, go home!

Kuroba Shido limped upstairs, fumbled for his keys, opened the door, and went home!

Shimotsuki Airi followed behind Kuroba Shido, watching him limp up the stairs, then take out his key, open the door, and enter the room... She followed him in.

After following them inside, Shimotsuki Airi was quite cunning; without saying a word, she found a seat and sat down.

I began observing Kuroba Shido's house...

Wow, it's much worse than I imagined.

In other places, poverty limits imagination, but in Shimotsuki Airi's case, wealth limits imagination. Shimotsuki Airi never imagined that people could actually live in such a place.

A leaky ceiling, an uneven floor, a dilapidated tatami mat, and walls that reek of decay...

This was the first time in Shimotsuki Airi's life that someone was so poor, so she was very curious and kept looking around at everything, just like a curious child.

Soon, Shimotsuki Airi found something to praise, such as...

Despite how poor Shido Kuroba's family was, the trash can was quiet, and there weren't mountains of garbage or uneaten food piled up like in some anime...

Hmm, not bad, you could be considered a clean person, albeit somewhat.

Is that really the case?

It's an egg!

Is that a matter of cleanliness or not? It's like the landlord's family has no surplus grain. Kuroba Shido is so poor, where would he get the money to buy groceries and cook?

The whole family of Dahei spent all the money they could buy.

Kuroba Shido had previously tried leaving his plates unwashed after eating, and when he checked back two days later, he found the plates were reflecting light...

If nothing unexpected happens, it should have been licked clean by the big black family.

That's so brutal!

Given how things are already like this, how could there possibly be any trash left?

Food utilization rate: 100%!

After Shido Kuroba finished eating, the Kuroba family ate. What was left over was for the other animals in Shido Kuroba's family... Oh, sorry, there wasn't much left after the Kuroba family finished eating.

Xiaoqiang couldn't even survive in Kuroba Shido's house because he was no match for the entire Kuroba family and was simply chewed up like an energy bar...

Big Black: I don't care where you're from, just talk to my stomach!

Shimotsuki Airi sat quietly to the side, while Kuroba Shido was tinkering with a running wheel for Daikoku in the kitchen. The kind for hamsters definitely wouldn't work; as soon as Daikoku put its big stomach on it, the wheel's bearing burst open!

So, Shido Kuroba is now modifying the treadmill for Daikoku himself. He does have protein powder at night, but he can't bear to buy it.

I plan to visit the principal's office when I go to school tomorrow...

"Alright, come on, Big Black, go run a couple of laps and see!"

Kuroba Shido turned the oversized hamster treadmill in front of him around... no, it should be called a wild, original-furry fancy rat treadmill!

Big Black hugged its belly and took a couple of steps. The bearings creaked and groaned under the strain, but it could still hold on.

Kuroba Shido poked his smooth chin: "No, I guess I still need to buy a treadmill. It'll be good for me to get some exercise..."

"Big Black, you run ahead, I'll go feed your wife."

Big Black walked there slowly, hugging his big stomach. Black Feather Shido carried his schoolbag and walked towards the corner of the wall. He opened the schoolbag and took out the crayfish and rice balls that he had packed from the restaurant earlier.

"Knock knock!"

Kuroba Shido knocked on the corner of the wall: "Little Kuro, little Kuro, dinner's ready."

A squeaking sound came from the corner of the wall, and a heavily pregnant female mouse emerged from the corner. She cautiously raised her head first, and then Little Black tried to rush out, but was held back by the mother mouse with her tail.

After confirming that it was Kuroba Shido and that there was no danger, he came out.

"Extra food today," Shido Kuroba said, then packed his bag and prepared to continue training Daikoku. It was still early, so playing some games was a good option.

Not all mice are intelligent. Some, like Big Black, can communicate without any problems. But Big Black's wife and son aren't very smart. Big Black's wife is somewhat intelligent, but only to the point of being able to distinguish between good and bad. As for Little Black... he's completely useless.

He's so hungry he'd even eat his own father; he's hopeless, this unfilial son.

I wonder if Xiao Hei will become as strong as Da Hei Ye if he manages to deal with some nuclear wastewater in the future...

"Forget it, never mind, I'll do some farm work." Kuroba Shido was about to find a chair to sit down and play games when he suddenly stopped as he passed by the living room. A person was sitting in the living room.

Ok?

Wait... if I'm not mistaken, he seems to live alone at home, right?

What was that we just saw...?

Kuroba Shido remained silent for a moment, then took two steps back to the living room, turning to look at Shimotsuki Airi, who was sitting on a stool with her eyes full of curiosity.

Shimotsuki Airi felt a little nervous and guilty after being discovered, and finally pouted, "I didn't do it on purpose, I just came in because the door wasn't closed..."

He spoke softer and softer.

The Black Feather Warrior said, "..."

Awesome!!!
