Makes me wonder if ZUN messed up and picked the looks of a different deity/buddha/whatever and the name of another.
For example I remember some buddhist(iirc) picture with a deity holding a sword up, while others had the sword close to the body like Fudou Myouou.

>QWERTY and たていすかんな (I guess it's called) layouts,
たていすかん I guess, I think the な is just to make it an adjective.
In Neko Project all I see is it having the QWERTY + たていすかん option aka you write romaji or one kana per key.
But that's just in the console of the pc98, there seem to be some programs to get kanji into it but I'm not sure if it was via kana input only.
