Tsuna inherited the family estate before he was even an adult: [a mental hospital].
Yes, it really was [a mental hospital].
After realizing there was no hope of selling it, he began carefully treating the people inside, hoping they would be discharged so he could close [the mental hospital].
But the number of “people” did not decrease. Instead, it kept growing...
[a mental hospital] has two departments.
The department on the left is called “What a coincidence, running into you again. Let’s make plans next time.”
The visitors coming and going are all jujutsu sorcerers and curse users.
The department on the right is called “Hurry up and leave. Don’t let anyone from the left department find you.”
The visitors coming and going are curses who can communicate with the director (Tsuna) without any trouble.
