Plot
The world domination AI "A.R.G.O.S." exploded so impressively and the Neo-Saitama was saved.But shortly after the great explosion, Steam-verse Neo-Saitama was created by someone.
The EMP storms came again from there and now the boundary of each universes became unstable than before.
This is not a natural EMP disaster. Someone must be trying to destroy and ruin the whole universe.
"Wow, It's not good"
I, the Vertigo, the great multi-verse traveller ninja, noticed the very bad omen. Seriously.
"I have to summon the brave fighters to this Steam-verse Neo-Saitama...!"
