Those "linebarrels" are not made of "iron."
Emi, The Boobpad.
Rising FUNimation star Josh Grelle, who voiced Wallflower lead Kyohei Takano and Kenichi: The Mightiest Disciple's titular hero, will star as Kouichi, a high school boy who gains super-strength and other such powers after an accident involving a satellite falling from orbit. Kouichi later also gains amnesiac Emi Kizaki, played by Alexis Tipton (her first lead, after playing Yuuri Andou in Bamboo Blade and Aira in Tower of Druaga) and a mech: Linebarrel. Here's the full cast list.
Caitlin Glass is set to ADR direct, with Mike McFarland assisting. And if that's not enough information to get you interested in the series, good news for those of you who buy anime from Right Stuf: if you pre-order part one of the 24-episode series, you'll get a free Emi mouse pad. I thought it was an oppai pad with squishy breasts, but Right Stuf's Alison swung by to correct me. Alas!
EDIT
and now that the picture has loaded i'm guessing it's not a series meant to be taken seriously\, though i may make a short video from clips of the anime with the Barrel audio
