The Spiritualist from the Next Class Over is the eighteenth chapter of Volume 2 of The Disastrous Life of Saiki K (Saiki Kusuo no Sai-nan) published on the 4th of December 2012.
In the school, everyone's excited about the new transferee who can see their spirit guardians however Kusuo isn't the least happy about it and decided to confront Reita. As he calls Reita in the restroom, Kusuo threatened Reita with a tissue that he hardened and formed into a weapon towards Reita who then felt scared at him. Abiding Kusuo's will, Reita felt like a new guy being bullied by a delinquent on his first day of school. When Kokomi suddenly passed by him, Reita started to tell Kusuo how unfair it was for him to be the only one to see Kokomi's naked body but when the female students rushed to Reita, he changed his mind and says he is okay with his powers. The male students starts to hate Reita as he gives vague answers to them but gives specific answers to Kineshi and Shun while in Riki's case, Reita ignores him the whole time until the moment they went home and he realizes how Riki isn't a ghost. In the temple with Kusuo, Reita gave him explanations as to why he has mistaken Riki for a ghost. It then was revealed through Kusuo's psychometry that Reita had Riki's father as his spirit guardian.
