Oh, Mrs. Mizuki Hitoshi doesn't look too happy about those kcals

Copying bonus info over from the uncorrected version:

The Black Thunder was delectable! We also got a big laugh out of the tag line "One look at this chocolate, and you'll know what duty is."

Reader-added tags include "Nakapanda-san suspected as member of the System", "The arms of the System reach all the way out here!" and "Kogasa-san seems happy, so isn't that what's important?"

The survey knows Black Thunder strikes in many ways:

Which Black Thunder should we go with?
• Black Thunder
• Black Thunder Minis
• Black Thunder Steamed Buns
• Morning Thunder
• Hand 'em all over!

The System knows where you are going, Sanaewife. You can't hide Kogasa-san from the System!!

For the poll, just hand 'em all over. They'll be taken care of... Somehow.

The tag line of Black Thunder actually means "The chocolate that anyone recognizes is giri-choco (obligation chocolate) at first sight".
It's rather well-known that Japanese women give chocolate to men on Valentine's Day, but not only to their lovers, they often give chocolate to their co-workers and superiors out of obligation. Nobody believes this cheap Black Thunder is the expression of true love. :P

I wonder how many people are gonna give him Black Thunder at Reitaisai tomorrow now? The gift I was going to give him still hasn't come in the mail... Maybe I'll pick up some Black Thunder on my way to Odaiba :)
