"The host's strong dislike is detected, the system enters the cooling down period, and the system can be unlocked by completing the tasks cumulatively. During the cooling down period, the host's age is punished to remain 30 years old..."

"???????"

In the second year of Konoha, Uchiha Madara, who was about to leave Konoha, was stopped by a curly-haired man. Uchiha Madara's face warmed up.

"Cousin, you don't have to persuade me, I'm determined to leave."

"My cousin, you are poor but rich, and there is nothing I can do to help you. Take these things with you, and don't wrong yourself when you go out."

Uchiha Gin stuffed a storage scroll into the other party and said goodbye with tears.

A few years later, Uchiha Madara, who had just captured the Nine-Tails, accidentally opened the scroll given by his cousin during his break. Looking at the piles of gold bricks and several ninja tools he had never seen before, he fell into deep thought.

"Dad! Run! Mom is catching up!"

"Running as fast as I can!"

"Stop right there, you two! I told you not to fight in the house! My favorite vase! Blade One Yang!"

"Ahhhhhhh!" X2

Jin: Brother Kaido, Big Sister Lily and Miss Yamato are fighting again.

Quinn: It seems that Brother was training Miss Yamato and broke Big Sister's favorite vase.

Everyone: That's no wonder (covering face)

(The author was disgusted by the clowns in Wano Country in One Piece, and opened this book because he likes the character Kaido. This is a newcomer's work. If there is anything wrong, I hope you can point it out.)

My dear grandpa is actually a werewolf, the truth behind the Philosopher's Stone, and the back-up man behind the four founders.

None of this prevents Loren from being a bastard, having fun with Seamus, exchanging experiences with the twins, and explaining the weirdness of Quidditch...

This is a story about hanging out at Hogwarts.

Sherlock Forrest, who had just crossed into the world of Harry Potter, did not have a golden finger and did not inherit the memory of the original owner, looked at the Hogwarts letter of appointment in his hand, and pouted.

“Just a Defence Against the Dark Arts professor.”

…

A few years later, the Daily Prophet conducted an interview with Harry Potter, one of the ten outstanding talents in the wizarding world of the 21st century.

“When was the happiest day of your life?”

There was an uncontrollable smile on Harry’s face.

“It’s the day after Professor Forrest cursed me that I would be taken away by You-Know-Who tomorrow.”

“Uh…what about the day you least want to go through?”

Harry suddenly turned gloomy.

“Every Christmas.”

“Why is this?”

He covered his face in pain, and even couldn’t help sobbing.

“Woooooo…because on that day, Professor Forrest will wish me a Merry Christmas!”
