Methuselin (メトセリン Metoserin?, Yen Press: Metoserin) is a drug that is briefly mentioned by Touma, as a drug used in the Power Curriculum Program.[1]


The katakana used for Methuselin is similar to that used for Methuselah (メトシェラ?), the oldest known human character in the Bible, the son of Enoch and the grandfather of Noah.

The name is apparently a pormanteau of "Methusel-" and the suffix "-in".


Part of the Power Curriculum Program, it is apparently in pill form,[1] and due to its use of the "in" suffix, apparently denotes that is probably a pharmaceutical product, or protein.[2] It is most likely a mind altering substance that aids the user in achieving Personal Reality, though this is just speculation.
