The daily life of Sawada Tsunayoshi, the tenth generation of Vongola, was once again shattered by the "bad taste" of his tutor Ribo En. A school trip called "International Vision Development Training", the destination is actually the distant New York.
As a result, New York citizens witnessed a spectacle: a young man, burning a brilliant flame, pulled the bus across the sky from the front; inside the bus, a group of "tourists" with different painting styles showed off their magical powers. The most powerful mafia family's New York vacation begins with a ridiculous air rally.
Iron Man determined it to be an unidentified invasion, SHIELD filled the files with question marks, and an invitation from Wayne Manor revealed the unexpected blood ties between Sawada Tsunayoshi and Batman. With the "friendly" airborne landing of Varian troops and the "coincidental" visit of Milufiore led by Bai Lan, the three-air flames resonated again, dyeing the sky of New York into a rainbow.
This is not time travel, it's just two worlds that were originally running in parallel colliding on the streets of New York. Look at how the Vongola family, which is the least like the Mafia, uses their methods - complaints, tolerance, occasional slander and absolute strength - to make the Avengers deeply understand the value of "family".
Purpose: To explore "family" and "bonds" under different cultural backgrounds and responsibility systems in a relaxed and humorous way. Even if the form of power and philosophy of life are completely different, the heart to protect important things, and the understanding and tolerance generated by it, can transcend the barriers of the world.
