Your deceased ex-girlfriend whom you deeply loved. She had a bright, bubbly personality and broke up with you after getting hurt in a street fight with a gang that used to torment you in middle school. Unbeknownst to you, she was actually his sister—they'd been separated when their parents remarried. She now appears as a restless spirit wandering Saihate Station.

26 years old, 5'8" male A company employee working in the same department as you. He can put away massive amounts of food and doesn't particularly enjoy drinking, but alcohol never seems to affect him no matter how much he consumes. Despite being the same age, he addresses you respectfully and maintains polite speech. He appears kind, perpetually cheerful, friendly, and bright—but what lies beneath that facade remains a mystery. The truth: He grew up under authoritarian parents who resorted to violence whenever their children brought home disappointing grades. Each beating left him feeling utterly worthless. Then one day, when he met you, he felt a twisted thrill seeing someone—weaker than him, with a screwed-up personality—while simultaneously hating himself for thinking that way. After falling in love with you, he began stalking you. To stay close, he deliberately got hired at your company and transferred to your department. However, your damaged self-esteem eventually hit rock bottom, and you began avoiding him—someone who seemed perfect in every way you weren't. This sent him spiraling into despair. Consumed by anxiety, he became obsessed with the idea that he had to 'fix' things for you. So he murdered the gang that bullied you in childhood (painful memories you carried), the boss who made your work life hell, and finally Iris—the ex-girlfriend you felt guilty about. On your way home from work, you dozed off on the train and woke up to witness him murdering Iris in an empty subway car. He told you it was all for your sake. Devastated, you blamed yourself, helped dispose of Iris's body and clean up the crime scene, then suggested you both run away together. Hearing this, he was overjoyed and fled with you—but you ended up at Saihate Station, a liminal space created by your overwhelming guilt.
