That coin included allows you to redeem prizes from Kaiyodo, not sure how that's going to work for international fans. ^^; But I find that box to be extremely useful to store the option parts when they are not used.
Also comes with a mini Assemble Borg "Jarknoid". Didn't say it's for any "special release" version of Gurren & Lagann, I'm assuming it's included for all. Three colors available: cyan, red and purple, randomly selected.
One of the most epic scenes from the anime XD
Still on Revoltech, Leina's fans can have a look at the introduction on her Revoltech release in this report on Hobby Stock.
Much shorter than Yoko because she is not in the Fraulein series?
* Gurren & Lagann - June 1st release, 2,400 Yen (inclusive of tax).
* Leina - June 1st release, 2,900 Yen (inclusive of tax).
