Senpai, Jitaku Keibiin no Koyou wa Ikaga desu ka?

Hajime Tamachi drifts through his days with a profound sense of apathy, untouched by the highs and lows that animate those around him. His quiet, uneventful routine takes a disorienting turn, however, when his phone lights up with a message from Renafalt—an enigmatic online gaming partner he has fought alongside for five years, yet whose real identity remains a complete mystery. The message contains a bizarre proposition: "Senpai, how about hiring a home security guard?" Though baffled, Hajime—who goes by "Tama" in their virtual circle—is absolutely certain that Renafalt is undeniably a man. Trusting this conviction, he agrees to a face-to-face meeting, expecting to finally shake hands with a fellow male gamer. Arriving at the crowded meeting point, his gaze locks onto the prearranged marker: a conspicuous red suitcase. But the person attached to it leaves him utterly frozen. Standing before him is not the gruff comrade he anticipated, but a stunningly beautiful young woman with an unmistakably feminine figure. Her demeanor is hesitant, almost shy, as she nervously clutches the suitcase handle. When her eyes meet his, she breaks the tense silence with a stammered question: "Ah... A-Are you... Senpai?" That single, trembling inquiry shatters Hajime's long-held assumptions, plunging him into a bewildering reality where his trusted friend is now a charming stranger—and she has just proposed an arrangement he never saw coming.
