Sally O'Brian is delighted when she is asked to help the children at the school where she had taught for most of her career to plant a vegetable garden. The portion of the school yard where the Principal wanted to place the garden was wasted space, a large mud pit that had filled with water after the recent winter rains.She and two friends work out the details of how to drain the water, then fill the pits with extra soil to level the area out. It's a great plan...until she hears a voice calling to her. "Help me!" cries an ethereal voice that only Sally can hear. Then, as the water level recedes and the mud is scraped away, the eighth graders uncover a human hand. "Get the children back inside," yells Sally. She certainly can't allow the children to learn that there's a ghost in the garden.

All Sally O'Brian wants is a quiet Christmas. Yes, she wants to rent out her newly renovated and re-furnished Cliff House for the holiday season, but that goal is secondary to just spending some quiet family time with her daughter Jennifer, her son-in-law Jack, her delightful granddaughter Kiera...and her dead husband Matthew. But then she learns that her daughter has invited a whole host of family members to come and celebrate Christmas with them. While this normally would be a great source of joy for Sally, she's discovered a terrible secret. The ornaments she's bought to decorate the Cliff House where all her relatives will be staying are haunted. And the ghosts that haunt those decorations are the kind of ghosts that like to play tricks on the living. Sally is afraid that this will be one Christmas no one wants to remember.

Sally O'Brian sees ghosts. Not because she wants to. But when someone tried to kill her and her husband, she discovered that while his time had come, hers had not. Now she was back in this plane of existence, but this time with a mission. Her role in life was to help those who could not pass over to the other side to do so. And that mission included the plaintive voice of a young teenager who had witnessed the murder of a young man in the Cliff House. And the ghost was willing to help Sally solve the current-day murder, but only after Sally had found out who had killed the unfortunate teenager eighty years earlier.

As the war for the Evil God's vessels begins to escalate, an even more terrible threat comes to Seishin City. When Natsuki runs away, fearing for her life, Yuichi and his friends try to search for her. Their pursuit will lead them not only a new, deadly enemy... but a final understanding of how Yuichi came to have Soul Reader!

Between a secret battle to reassemble a dismembered evil god and a threat from destiny-altering beings waiting in the wings, the world's strongest little brother seems to have enough on his mind. But there's even more waiting in store for Yuichi Sakaki, and things are about to get more chaotic by the week. Soon, a yakuza gang is stalking his little sister, a demon doll is stalking Aiko, an overzealous archer is stalking him... and that's only the beginning!

The Divine Vessels War is reaching its conclusion. But with Soul Reader gone, Yuichi wants nothing more than to drop out! But will he really be able to go back to the normal life he's always wanted? And if he does, will Mutsuko ever speak to him again?!

One day, first year high school student Yuichi Sakaki suddenly awakens the power of "Soul Reader" within him, and he can see words above peoples heads that describe their true nature! With just a glance at the people around him, he sees crazy things like "Zombie", "Witch", and "Vampire"... That would be bad enough, but then there is "Serial Killer" Natsuki Takeuchi walking straight toward him... Nobody would ever believe him! Well, except for his older sister Mutsuko: This kind of stuff is right up her alley.

Yuichi hasn't yet unraveled the secret behind his magical sight, but the end of his first school term is still as busy and can be! He's got survival club activities led by his big sister Mutsuko, early morning combat training with the serial killer Natsuki Takeuchi, and a first date with the vampire Aiko Noro (with his little sister tagging along, for some reason). Then, in the midst of it all, Aiko reveals that her big brother Kyoya – whose world domination-plotting middle school syndrome has been growing worse and worse lately – has gone missing!

Yuichi, and the survival club are finally heading off for their summer training camp, to a luxurious villa in a remote seaside resort. Will anime-style swimsuit episode shenanigans ensue? If his big sister has anything to say about it, yes! But while the gang enjoys some much needed fun in the sun, a darker plot lurks just offshore. The world's strongest little brother is about to face his greatest challenge yet!

Yuichi's not-very-restful summer vacation came to an end, and the new school term isn't looking much better. Immortal demons are trying to kill him, his new teacher is a superpowered sociopath, and all kinds of bizarre events are happening around the school. What does Kanako's new novel have to do with the bizarre goings on at Seishin High? Once again, it's up to the world's strongest little brother, and his highly delusional sister, to find out!
