okay so apparently she isnt the only one. Maybe it's the movies mode only goes up to E? I'm not sure really someone should mention this to TN
EDIT: After doing some more looking, i noticed that yes in movies mode it only goes up to E universally. This though, really is only a problem for That particular outfit, and for only Lei Fang ayane kasumi and kokoro because Ayane and Leifang have 4 hairstyles with and without a mask, and Kasumi and Kokoro have 5 hairstyles.
SECOND EDIT: Kasumi and Kokoro also only have 4 of their 5 styles in the ninja outfit with and without a mask. Kokor's second bead choice is not there, and Kasumis Blue Ribbon isnt either.
Most everyone else has like 2 or 3 different hairstyles. TECHNICALLY Kokoro would (or should) have the most with 6 hairstyles, but they removed one of the four beads she had with her default hairstyle so she only has 5.
one more note: You would think that 4 different hairstyles is nice but....TN basically only uses (for most everyone) one of these styles:
Braid (of some kind)
Pigtails
Loose (either as straight, or in some other style like with Christie and Momiji)
Ponytail
Also Kasumi uses everyone of the above styles:
Her default is a ponytail
Second is braided Ponytail
Third is loose
Then the ponytail with blue ribbon
Then the side ponytail (which techincally is a single pigtail in a sense)
Okay one more edit:
The only other "style" in the game is the short style, used only by a few characters (mila tina and lisa as well as christie to be exact) as well as the two "unqiue" styles TN gave to Lisa and Mila for DOA5LR which is Lisa's white colored hair and Mila with the hairclips (which I actually think looks good for her)
One other thing I think should be fixed/given is the ability to choose multiple hair colors and glasses for every outfit, on the characters who have more than one of those.
