Fatal Frame 2: Crimson Butterfly’s haunting narrative draws players deep into a world filled with tragic spirits, but none are as compelling as the bond between the Itsuki twins and their sister Mutsuki. This side story enriches that fragile connection, offering a rare glimpse into the ghosts that linger not to harm but to help. Unlocking this late-game chapter adds emotional weight to the journey and sheds light on brotherly loyalty amid the eerie village ruins.
Itsuki and Mutsuki Side Story Walkthrough
The final chapter begins with Mio separated from Mayu, confronting three hostile villager spirits at the Kureha Shrine. After fending them off, descend the stairs. If no ghosts pursue you, you’ll witness the apparitions of Itsuki and Chitose heading toward the Old Tree — a familiar landmark from the previous chapter where pivotal memories unfold.
Slip back inside the Old Tree and ready your Exposure Lens. Photographing the scene by the Pinwheel Puzzle reveals the Remnants of Itsuki and Mutsuki. This triggers a heartfelt dialogue revealing Itsuki’s conflict over how to tell Chitose about Mutsuki’s passing. Your journal will update with new, crucial entries reflecting this poignant moment.
Next, retrace your steps back to the upper levels of the Kureha Shrine. Here, a ghostly Itsuki tries to help Yae and Sae escape the village—capturing this through your Exposure Lens summons another journal update. Inside the shrine, snap a photo of Itsuki returning alone, adding depth to the unfolding story and further journal insights.
Proceed to the Storehouse, the grim site where Itsuki was imprisoned throughout much of the game. Use your Exposure Lens once more to capture a Remnant depicting Mutsuki watching over his brother during his isolation. These moments enrich your understanding of the brothers’ bond amid the village’s despair.
Completing this final photo unlocks a Spirit Stone for your Spirit Radio, providing access to Itsuki’s introspective thoughts. Though brief, this side story packs emotional resonance. If you previously finished Chitose’s side story at the Tachibana House, completing this one will instantly unlock the intertwined Tachibana Family Side Story, deepening the game’s lore experience.
