Corporate Slave Ojisan Buys Tentacles

Corporate Slave Ojisan Buys Tentacles (Japanese: 社畜おじさん触手を買う), also known as Salaryman Buys Tentacles, is a yaoi (BL) manga by Itsume Eruko (Luc) blending the bizarre—think tentacled creatures, psychological manipulation, and erotic horror. Classified under Adult, Hentai, Smut, Violence, Monsters, Office Workers, Psychological, and SM/BDSM/SUB-DOM genres, it’s clearly intended for a mature, niche audience.

Tamaru Masashi, the protagonist, is an overworked “corporate slave” looking for relief from his stressful office life. In search of comfort, he purchases what’s described as a “space plant”—a pet plant that supposedly wiggles its tentacles and moves autonomously to find nutrients.

In Part 1, after a long night of work, Tamaru falls asleep—and wakes up to find the plant crawling on his body, exhibiting unnervingly intimate behavior.

Part 2 reveals that Tamaru’s plant isn’t an ordinary novelty—it’s a rare, parasitic species. Faced with this, and unable to simply resign from his corporate grind, Tamaru enters into an uneasy agreement: he’ll become a “host” or mate for this creature, named Hani, in exchange for cooperation in research.

Ayakawa, the researcher overseeing the experiment, is portrayed as morally ambiguous—intrigued by both Hani and Tamaru in ways that go beyond simple scientific interest. Tamaru finds himself increasingly manipulated by both Hani’s intimate parasitism and Ayakawa’s unsettling control.
