The Unlimited- Hyobu Kyosuke [TV]

In the spin-off, The Unlimited – Hyoubu Kyousuke, much of the anime is spent building the character of Hyoubu with an additional 2 episodes of his back story (episode 7 and 8) which reveal some aspects of the plot that you might not have been initially aware of. (So don’t skip the two episodes because you just want the action!)
