It’s nice to have a partner who values your hobby, but not like this.

It’s never easy when a romantic relationship reaches its end, but it’s particularly painful when it happens with live-in lovers. Even among that subset of breakups, however, things have got to be especially awkward for Japanese Twitter user @wkkazuya.

The 49-year-old @wkkazuya had become involved with a 23-year-old woman who was living in a dormitory owned by the company she worked for, which isn’t an unusual living situation in Japan. She decided to quit her job, though, which meant she needed to find a new place to live, and so she ended up moving in with @wkkazuya, who lives in the city of Akashi in Hyogo Prefecture, not far from Kobe.

@wkkazuya is a pretty big anime fan, and a physical media collector to boot. Like a lot of people with those passions, he’s got a few shelves in his home filled with his personal treasures. And while that sight probably filled him with satisfaction, he was a lot less happy when he noticed that some gaps had suddenly appeared on his shelf, with a number of his prized DVDs and Blu-ray discs missing.

With no one else having access to the discs, @wkkazuya suspected his girlfriend was behind their disappearance, and contacted the police on November 24. Although she initially claimed that an acquaintance of hers had stolen the missing anime, during questioning she admitted that she indeed made off with the discs and sold them at a local branch of Geo, a retailer that deals in second-hand anime, video games, and CDs, for a total sum of roughly 90,000 yen (US$800), saying “I had no money, so I stole them.” She has now been formally placed under arrest.

According to @wkkazuya, among the pilfered anime were a limited-edition first-pressing Blu-ray box set of Sora no Manimani, an unopened first-pressing complete Blu-ray set of Android Kikaider, an unopened Blu-ray set of Darker then Black, and a limited-edition Blu-ray box of True Tears.

The betrayal could have been worse, though. As shown in another photo, @wkkazuyas’s box set of Azuki-chan, as well as his set of Tokyo Pig, were safe, having been kept in a separate room.

While the stolen goods have been recovered, they’re currently evidence, and so are being held by the authorities. Unfortunately, @wkkazuya claims that the discs which were unopened while in his possession have since been opened, which would severely affect their value in the collectors’ market (it’s not clear whether the discs were opened by his girlfriend, the Geo staff, or police investigators).

The incident has caused @wkkazuya to think his girlfriend was the reason several other items, including cash, have gone missing from his home recently, although for the time being it’s only the anime he’s made an official complaint to the police about.
