The second installation of 3DS ninja breast physics simulator Senran Kagura, Senran Kagura: Burst hit stores in Japan on August 30.

The game features even more of that fast-paced, sexually-charged ninja action that fans praised in the first title, which means many Japanese gamers have had their hands full these past few days, if you know what I mean.

Luckily, publisher MarvelousAQL has teamed up with sexual health product manufacturer Akahige Yakkyoku to boost player’s mojo with their new Senran Kagura “Round Two” sexual stimulant energy drink.

The Round Two energy drink is one of Akahige Yakkyoku’s more popular products and, as the name suggests, is designed to help men keep their libido strong after finishing “round one”.

This limited-edition Round Two features original Senran Kagura packaging and can be purchased at Akahige Yakkyoku retails stores around the country for 1,565 yen (US $20) per bottle or 2,980 yen (US $38) for a two-pack.

MarvelousAQL and Akahige Yakkyoku actually did the exact same promotion back during the release of the first game and one of the bottles in the two-pack features the artwork from the first crossover.

Only 1000 bottles are available, so quit playing with yourself your 3DS and get to your nearest Akahige Yakkyoku before supplies run out!
