Ultraman: Kaiju Girls, Activate!

(Original Ultraman + original worldbuilding + Ultraseven, not Ultraman Seven + suspend your disbelief) Moroboshi Xue transmigrates and is astonished to discover that he's been raised by Ultraseven. Uh-oh. Is this evil walking-stick alien going to make a move on me? But luckily, this is the original version of Ultraseven... Wait, what do you mean, luckily? This Ultraseven is even scarier! And why are there monster girls in this world? Why is there a Zetton following me around? Anyway, I'm no good at writing introductions.
