In CovertJapan, character birthdays are not mere trivia—they are narrative devices woven into the game’s alternate-history setting. Kuroe’s birthday, celebrated on November 15th, serves as a pivotal anchor for his backstory.

The CovertJapan community has spun elaborate theories around Kuroe’s birthday and relationships. Three popular ones include:

While the protagonist is her primary romantic interest, Kuroe’s relationships with others highlight different facets of her character.

Arguably the most emotionally devastating storyline centers on a former partner of Kuroe’s—a woman named Saya who disappeared in the line of duty. When a new mission suggests Saya may still be alive but turned rogue, the MC must help Kuroe confront his greatest failure. The romance here is not about new love conquering all, but about healing old wounds.

Kuroe repeatedly tries to push the MC away, convinced he is cursed. The climax involves a choice: help Kuroe save Saya (who may be beyond redemption) or let her go. The romantic payout comes after the mission, when Kuroe finally breaks down. For the first time, he seeks comfort rather than solitude. “I thought if I let you in, I’d lose you too. But losing you without ever trying… that’s worse.” This route provides the deepest character development and is highly recommended for players who enjoy crying.
