Watashi no Housekibako (私の宝石箱)

"Watashi no Housekibako" (私の宝石箱) is the first ending theme of the 2013 television anime Outbreak Company (アウトブレイク・カンパニー). Mai Fuchigami performs the song for the series, which was animated by feel. and originally broadcast in 2013.

Musically, the piece sits in J-Pop, favoring a light, polished arrangement and a gentle mid-tempo pace over a heavier dramatic approach. Its melody moves with a soft bounce, and the vocal line stays clear and intimate, giving the ending a calmer finish after the series' busier comic and fantasy scenes.

That tone fits Outbreak Company's mix of court politics, fantasy-world culture shock, and otaku comedy. Where the series often plays its premise broadly, the ending narrows the scale and leaves a more personal aftertaste, matching the story's effort to build trust between people from very different worlds. The song also carries an extra connection to the anime because Fuchigami voices Petralka Anne Eldant III in the cast.
