Unless I'm mistaken on the source, I think this artist has an existing tag under machi fuka already, I've added a bunch of their Fafner work in the past.

Not entirely sure how the two should be reconciled though.

Don't worry about it. I'll just put the deepstrait stuff under machi fuka. Their signature's already under most of the pictures, anyway.

Why does Yuusei look so good in a Synergetic Suit???
