Is that the Root ? She reached the Root by delivering message so hard ? I thought you have to do a sacrifice of 7 super ghosts to the Holy Grail to do that.
Yoshida is just too workaholic to abandon the job she is given to. So as long as it fits the job description, she will just do it even if it disrupts anything the recipients was doing in this case.
The question is how she manages to go to multiple places that supposedly can only be accessed by deity level existences.
And I 100% believe Yoshida would be a dimension-breaking reality-bending being, sorta like Bugs Bunny, except only to deliver you a letter (and be cute)
While I like the elf girl the best, I have grown to appreciate the two magic users.
Hopefully they'll stick around - that massage scene was kinda funny.
