It's been a year since he left her standing in the woods after her confession and Mai had moved on - until he called. The office is reopened and the team gathered to take on one of their biggest cases yet. Hell hath no fury like a woman scorned takes on a whole new meaning when they are forced to deal with the aftermaths of one of the bloodiest love triangles in history.

It seems weird, but harmless, when SPR is hired to make the crying of a nonexistent baby stop. Though Mai loves babies and is more than willing to help, the crying can't be smothered, because how do you fulfill the need of something that was never technically alive?

Secrets, lies, death, ghosts. They found the body, now they're gone. He's trying to forget, She's trying to move on. What will happen when he decides to come back? There will be madness.

After his release from the hospital after the cave incident, Naru takes on a new, dangerous case involving a powerful monster. He hopes to find clues about his dead brother but instead, Mai and the rest of the team finally uncover the lies and truths he holds, as well as the new emotions he never wanted to reveal but can't control any longer when Mai goes missing.

Just before finding the lifeless body of Eugene, Mai confessed her feelings to Naru. But, her confession was met with rejection. No, it was more than rejection. It was complete dismissal. Now that they have parted ways on undesirable terms, will there ever be a time where they can make things right? Do they even want to make things right? (Rated T for mild language)

Shibuya Psychic Research begins investigation on what initially seems to be a standard case. However, when a strange shadow covers the house in question and Mai's dreams are no longer safe, the atmosphere suddenly turns to one of terror. Along with SPR, Naru and Mai must work quickly to figure out a solution. But how does one fight a dream monster? (Light NaruMai.)

Mai and Naru was ready to enjoy a leisure visit to Naru's parents in England over Christmas. Yet an unexpected visitor in the night threw a spanner in the works and they are needed on a case that's already proven itself dangerous. Travelling to London's most famous insane Asylum, they must separate the truth from the lies to solve the mystery and perhaps save a soul in the process.

AU. Naru ends up getting sent to a Japanese high school for an unknown reason and meets Mai who is beginning to develop her psychic abilities. Together they investigate the mysteries of the school together and end up getting closer in the process.

SPR's latest case has it all: love, betrayal, and deadly secrets. When the gang take on a ghost that seems to target specific people, they never suspected it would mean danger for one of their own…

As an investigator for SPR, Mai is used to seeing malicious spirits. However, their newest case may be the most dangerous one yet, especially as the haunting becomes more complex and confounding than ever. With Naru back for the first time in almost two years, Mai must navigate her feelings as well as the haunted house. With things not as they seem, can Mai survive to see the end?
