/jp/ - Japan/Anime

ITT we give a description that is unusually detailed but just ambiguous enough to refer to more than one character or show.

At least one of these shows or characters must be anime to keep this on-topic for the section. The other can be from western media though or also from anime,

If you guess 1 correctly, satisfactory result. If you guess both correctly, excellent result.

If describing particular events from a series or accomplishments by a character, extra credit if you can also specify episode data like season/number/date/title although that's not really needed and could be overkill.

Feel free to spoiler-hide your answers if you don't want to reveal details about some shows to people. People willing to risk being spoilered can opt to view the text.

To get the ball rolling…

>An ancient demon imprisoned by a wise elder is released

>Demon manages to defeat badass elder

>Big Bad Demon has gathered a bunch of powerful allies and has established an impenetrable base

>Transform your own home base into a giant robot to assault the enemy's base, battle giant enemy in hand to hand giant vs. giant combat.

Who are we?
