The Portuguese title translates as April 1st, the date associated with Watanuki in xxxHolic, the manga and anime series created by CLAMP. Watanuki is a high school student who can see spirits and works for the witch Yuuko, a premise that made the series a lasting favourite among anime fans. Short character clips like this one circulate on soundboards and in fan edits, where a recognisable voice can instantly signal an anime reference. Its seasonal title keeps it useful every April, especially for jokes built around pranks and surprises.
