"You just can't rein in the fun when Haruhi-chan's involved!! Normally April Fool's Day is a time for good-natured pranks, but with Haruhi's power, any trick she pulls could threaten reality as we know it! While Koizumi struggles to organize the SOS Brigade to prepare for her antics, Haruhi is busy thinking up ways to recruit new members! Given the supernatural crowd already gathered in the clubroom, who knows what type of person Haruhi will summon to the SOS Brigade next?! If anyone shows up at all!! You'll find plenty of gags and guffaws as Haruhi dives into the world of four-panel and short comics!!" -- from publisher's web site
