I was farming the Tree of Life dungeon recently for a gong item, and I noted that Grandmother Raven's narration mispronounces Kagemoosha's name when introducing the end boss.
It should be kah - geh - moo - shah
She pronounces it kah - jeh - moo - shah
Presumably KI was going for authentic Japanese phonemes--in that case, "g" is never pronounced as "j." Other characters in the Spiral are consistent in this pronunciation rule, it just appears to have lapsed in this one instance.
This has always been on my mind since the first Mooshu run I ever did, writing about it now.
