Deep-fried chocolate tempura for Valentine's Day in Japan.

Black Thunder has collaborated with Hanamaru Udon to create a limited-time deep-fried chocolate treat called Black Thunder Tempura.

Alright, check this out: Black Thunder and Hanamaru Udon are joining forces to create Black Thunder Tempura—a wild concoction of deep-fried chocolate that’s crispy and sweet! From February 6 to 14, you can grab this tasty treat at 10 locations across Japan for just 100 yen. But here’s the kicker: each place is only selling 30 pieces a day, so you better plan ahead!

And if that wasn’t enough, they’re also running a giveaway for some Black Thunder Tempura-style blankets that look just like the dessert! To enter, follow both brands on Twitter and repost their promo tweets. You could snag a blanket, plus a whopping 320 pieces of Black Thunder candy or 10 free udon bowls. It’s a sweet deal, literally!
