[Kamen Rider Geats] Ultraman Is Forbidden from Fighting the Jyamato

(I'll get to this after I finish the Kamen Rider Geats fanfic next door)

Sawada Natsu: As an Ultraman host, why do I have to transform into a Kamen Rider to fight Jyamato?

DGP Management: Sorry, those are the rules.

Zero: (Breaks them in record time)

Mostly a fun everyday story about teaming up with Zero and various Ultramen to smash through the DGP, with everyone acting out of character together.

Heavy on the memes, though I don't even know what memes I'll use yet (?).

A crossover with a few other anime and (more than a few) Ultraman series, but the main setting is the Geats set.

Theme: Keep smiling, and good fortune will come your way. Haha.
