Assemble Insert In near-future Tokyo, a group called the Demon Seed has been antagonizing the city with its thefts and giant robotic Power Suits. After various failed attempts against the Demon Seed, the Special Operations Anti-Demon Seed Team (five men in a downtown office) begins to look for an idol to pilot a robotic suit against the Demon Seed. A talent show is held; and after a particularly dull line-up of contestants, the extremely strong Maron Namikaze is discovered. She is fitted with a metal costume and sent to take the Demon Seed down, all the while having an idol singer career forced upon her.
