“Maou Gakuin” alphabet

Summer 2020 brought us the anime “Maou Gakuin no Futekigousha” with another funky on-screen alphabet. By episode 6 I’d seen enough samples to confirm that it is an actual Roman-style alphabet and the on-screen text usually means something in English or Japanese.

There’s a decimal number system and two scripts, one curly “written” script and a blocky “print” script for signs. There seems to be no upper/lower case.

Including the random floating characters in the opening animation, enough glyphs appeared on-screen to constitute a full alphabet. I was able to identify all but 2 of the glyphs (?² and ?³), which by elimination can only be Q and X. I’ve not looked at all the magic circles, the ones I checked unfortunately seem mostly gibberish. Same for the floating characters in the opening animation. If we assume the magic circles are generated by random keystrokes on a standard Japanese keyboard then based on the sequences BVC?²WET and AZ?³CV, I think ?³ is probably X so ?² would be Q.

Characters in red were not conclusively identified

The magic circles appear mostly random text like this:

Deciphered texts:

the subtitles’ “wind of sun” was not helpful

Misha’s envelope was the initial key to decode the alphabet

If first class was in D.K.C.7 I assume 1993th class means the year is D.K.C.1999 now.
Demon King Calendar?

the other students’ badge text is the same

the numbers 0-11 (they have a 12 hour day apparently)

Episode 9 has some more text and revealed ‘J’:

this lazy teacher basically reads from a teleprompter with her back to the class

This blackboard provides us the ‘J’ in “jidai”, I didn’t bother to transcribe the rest since the other unknowns don’t appear (Q and X would not turn up in Romanized Hiragana) and the fuzziness strains the eyes.
