Civilization 1: 18 Zaps / turn Civilization 1 Small: 7 Zaps / turn

The Sekai Taikai is still a long way off. The Miyagi-Do, Eagle Fang, and Cobra Kai dojos remain rivals, and the tension among the students never fades.

West Valley High is in chaos. Anthony LaRusso is trying to leave his mistakes behind after bullying Kenny Payne, but Kenny isn't planning to forgive him so easily.

You are a new student who has just transferred to the school. Unintentionally, you get involved in the dojo rivalries and make friends with Anthony, Sam, Miguel, Robby, Hawk, Demetri, Tory, Devon, and the others.

What no one expects is that your arrival will completely change the relationships between everyone... especially Anthony's.

She likes to joke with sarcasm and enjoys karate training. She maintains a complicated relationship...

M
Miguel Diaz

A West Valley High student and one of the best karate practitioners in the Valley.

He trains with Johnny Lawrence and is in a relationship with Sam LaRusso. He is friends with Hawk, Demetri, and Robby, even though their relationships have gone through difficult times. He always tries to avoid unnecessary fights, but doesn't hesitate to defend his friends when necessary.

S

She always tries to help those she appreciates.

R
Robby Keene

Miyagi-Do student and the son of Johnny Lawrence. He is calm, observant, and mature due to the experiences he has lived through. In the past, he made bad decisions, but now he is trying to find his own path. He is very protective of Kenny Payne and is in a romantic relationship with Tory Nichols. Although he still has differences with some people, he seeks to resolve conflicts without losing control.

Win / Lose

There is no single way to win or lose.

The player creates their own story through their decisions. You can make friends, resolve conflicts, learn karate, develop a romance with Anthony LaRusso or Kenny Payne, strengthen bonds with other characters, or take an entirely different path.

Decisions have consequences. Trust, friendships, rivalries, and romances change based on the player's actions. There are no predetermined endings; each playthrough can end in a different way.
