Well, that's more of a technicality, since it covers his entire hand, too.

What would happens if actor who played Red Ranger walked out on Toei?

Just says he was scheduled to film 11th episode of Super Sentai but he's walked away and told Toei that he is done with Super Sentai

He says he is unhappy of Toei's treatment toward his co-stars, he wanting Toei to not give him so many toy stuff because he wanted his co-star to be equal to his character.

He is angered with the writer of rushing the story and doesn't like how his character were portrayed (His Red Ranger was a loud-mouth and annoying person)

How does Toei resolve this problem when their Red Ranger walked out on them and never came back to film the 11th episode?

Remember this actor told them that HE WILL NEVER COMING BACK AGAIN! That's mean he have NO DESIRE TO REPRISE HIS RED RANGER AGAIN!

Toei hire someone else. The show will go one because no one actor is bigger than it.

Not that I think that will ever happen. The Japanese have an incredible work ethic and most actors would see a project out to the very end and give 100% even if they weren't feeling it. Not to mention these shows are seen as stepping stones to the actors.

But what about previous Red Ranger? Are Toei going to kill his character off because he told them that He have NO DESIRE TO PLAY THAT CHARACTER AGAIN!

There are a lot of rangers that have chosen to never reprise their characters.
They merely keep them in their costume if they need that ranger to return (Voice work will be done by a different actor. They do this all the time in Hero Taisen movies).

Also, they can't just walk out. Actors have contracts for a reason, which basically ensures they have to see the series out for how ever many episodes are required.

Additionally, many actors use Sentai as one of their earliest stepping stones to get into the industry. If they walk out of a Sentai mid production, they're kind of creating a name for themselves as someone who doesn't have the determination/skill/attention/or whatever to see a 50 episode show to the end. It would be an unwise call to make, even if they don't like what they're doing, because it would be a gigantic black mark on their resume.

If you were a President of Toei, How would you convince him to NOT QUIT the show when he is unhappy of how the treatment of his co-stars, he is unhappy with the writer rushing the story and he hated the way his character is being portrayed as a loud-mouth fool?

If I were President of Toei, I would have a lot more things to worry about than one actor throwing a fit in Sentai :lol

But contracts contracts contracts. That's how I would convince him.

I imagine someone telling you, "if you break contract, you will either go to jail or be bankrupted for the rest of your life, and you'll certainly never work as an actor again," would be a pretty strong motivator not to quit. :lol

That and millions of children will see you as a traitor, causing your named to be cursed and dragged through the mud. As I, the president, will launch quite the smear campaign against you and the company representing you.

Or just send this guy and have him get the job done.
