Hayate no Gotoku Fan Buys 398 Copies of Shounen Sunday for Sakuya Card

The latest issue of Shounen Sunday came with a free Sakuya (a character from Kenjiro Hata's Hayate the Combat Butler) card that can be used in Hayate the Combat Butler TCG. New Akiba is reporting that a Hayate fan bought 398 copies of Shounen Sunday in order to get 398 copies of the Sakuya card.

Canned Dogs has more:

He had to travel to 82 different branches of 7-Eleven buying several copies of Shounen Sunday from each branch to complete the task (leaving a few copies so others can get their own copy) [...] 398 is a wordplay on the name "Sakuya", which is why he bought 398 copies.
