Earth Defense Force of Class 3-Z

[Ginpachi 3-Z + Ultraman + Crossover Grab Bag]

When Sakata Ginpachi discovers that every student in his class has been an Ultraman host at some point, he has only one thought:

As expected, only high schoolers have the energy to save the world.

A real wage slave just wants to lie motionless in bed after work.

That day, Kagura hears someone whisper in her ear: Please lend me your strength and save the world!

Sougo hears someone say the same thing: Super Beasts feel no pain.

The two of them: Got it.

That day, Shinpachi and Hijikata stand on the roof with Ryu Aihara, yelling at the red Ultraman:

What exactly have you been protecting?!

*

Sakata Ginpachi is in despair.

He tells the captain of the Earth Defense Force, who looks pretty reliable: So protecting the world is your job, right?

Genba nods. “Of course. But your students really are enthusiastic.”

Ginpachi gets a bad feeling. “What happened?”

Genba: “That guy named Katsura shouted, ‘So this is Unit Six!’ and charged inside.”

Ginpachi: “Wig, you idiot, get back here! That's the Earth’s ultimate weapon, the hugely expensive Asgaron! And why can your mech even let him in? Shouldn't it have some kind of security system?!”

Genba: “Maybe because... Katsura and Asgaron are both voiced by Akira Ishida? Even Asgaron can't refuse himself.”

Ginpachi: “...”

Forget it. Let the world be destroyed, he thinks, completely losing his mind when he sees a monster stomp his newly purchased, uninsured house, which still has thirty-two years of mortgage payments left.

Monster: I don't know! They charged at me shouting things like “peace on Earth,” “love and justice,” “our bonds,” and “give me back the house I just bought” (sob)
