Trivia

 * He claims that his chosen field of study in the Power Curriculum Program is psychokinesis.
 * There is an unnamed Level Upper user in Toaru Kagaku no Railgun that has the same background as Haratani, which is observing Gunha's fight with some delinquents. The fact that the character is left unnamed has created some speculation about him being Yabumi.
