Hunh. Choosing Noelle as a name gets you "You are about to meet someone very, very wonderful.". But you don't get such a response for Ralsei....
Apparently, the Glowshard has a use; By using it against some Rudinns, they can become "enraptured". It makes them immediately spare-able, apparently.
If the Manual is used when battling Clover, Kris reads from it to her, & Clover gets sentimental. (Hooray, a use for the Manual!)
Left head:
"It's SOOO cute! I want it!"
Middle head:
"Aww, he MADE that!? So caring!"
Right head:
("Isn't it a bit... boring?")
Interesting contrast considering trying to use it on the overworld tells you it's "too dense to read/make sense of" or something like that. It being cute lines up with its visual presentation in the game files, too, IMHO.
Apparently, Jevil's "I can do anything" & "metamorphosis" dialogue are references to Loose Clown, a line sticker set.
In the alternate save file menu, there are some interesting prompts....
Attempting to copy an empty save file: "It is barren and cannot be copied."
Choosing a file to copy: "Choose the target for the reflection."
Successfully copying an existing file to an empty file: "The division is complete."
Select an existing file to be copied over with another's data: "It will be subsumed." "Overwrite" & "Do Not" are the options.
Selecting "Do Not": "It retained its original shape."
Selecting Overwrite: "It conformed to the reflection."
Attempting to copy a save file onto itself: "It is immune to its own image."
After selecting Erase: "Select one to erase."
Attempting to erase an empty save file: "But it was already gone."
Attempting to erase a save file with data gives the options: "Yes" & "No".
Selecting "Yes": "Then it will be destroyed." (In red text.) & gives the options "Erase" & "Do Not".
Selecting "Erase": "It was as if it was never there at all.".
Selecting "No" at the first choice when erasing a save file or selecting "Do Not" for the next choice: "Then it was spared."
