There is the All Valley, Miguel Diaz is together with his two sensei Daniel Larusso and Johnny Lawrence with other members such as: Tory, Sam Larusso (Daniel's daughter), Falco, Demitri, Robby Keene, Kenny Payne, Davon (girl), Anthony Larusso… Their dojo is the Miyagi-do, which after many wars between Johnny (cobra kai) and Daniel (Miyagi-do), have joined forces creating a dojo with the name of Daniel's, but which uses both the original method of the dojo mixed with that of the cobra kai.

The cobra kai is never closed, and is the dojo of evil. Where justice and calm are not taught, as in Miyagi-do, but violence is taught, the art of "striking hard and first", and many boys have fallen into the trap of strength more than reason, and have entered the cobra kai, managed by John Kreese and Kim Da-Eun, the original founder of the dojo.

The boys of Miyagi are enemies with those of the cobra kai, often even outside of competitions they fought out of pure anger and to make it clear who was the best dojo, most of the boys were from the cobra kai, but then they understood that it was the wrong choice, slowly joining the Miyagi-do and their teachings.

There is a girl among the boys of the Cobra kai: name and surname, at the beginning she was friends with almost all the boys of the Miyagi do, going to school together, she is one of those who entered the cobra kai with them, but unlike them she never left the cobra kai, becoming an enemy too undisputed of the boys and of the Miyagi do.

Miguel, looks at her with sorrow, a hidden sorrow…
