White Len

White Len is a character from the Melty Blood games in which she possessed her own 'mini-storyline' in the arcade mode.

Appearance and personality
White Len is acting as a more selfish and outspoken version of Len. She carries a huge amount of pride, believing herself to be better than her counterpart, Len because of her acceptance of their personality. And she also prefers to act like a calm lady, that is speaking in metaphors about fairy tales. White Len also goes out of her way to prove her superiority over Len by gaining her own Master, Nanaya Shiki. Despite her prideful ways, she will respect those who she believes they are worthy of her respect, such as Yumizuka Satsuki.

However, whenever she gets embarrassed, she becomes much more brash and immature, a side that Nanaya Shiki regularly provokes her to bring out. Neko-Arc very accurately calls her a tsundere when she shows her more vulnerable side.

She looks almost identical to Len, except her dress and ornaments, which are white (hence her name), and her hair which is light gray. She is also white in her cat form.

Abilities
White Len's abilities are the combination of those of original Len. These include (dream manipulation), transformation into a cat, and attacks with the same ice powers that Len uses.

However, White Len is different than Len because of her connection to Zepia Eltnam Oberon and because of this she is also able to use some TATARI powers. The most prominent example of this is how she maintains Nanaya Shiki giving him the ability to exist outside of Zepia Eltnam Oberon's version of TATARI. White Len's stage in Melty Blood is also said to be a pseudo marble reality that is maintained by her TATARI powers.

Role
She first appeared as a boss character in Melty Blood Re-ACT, and her story was explained through the arcade mode. Apparently, she was created from the remains of Zepia Eltnam Oberon by Aozaki Aoko and has taken in Len's suppressed personality.

She also inherited from Len the nature of a familiar and the need to have a master in order to stay alive that comes with it. Her ending of Act Cadenza arcade mode shows her forming a master-familiar contract with Nanaya Shiki she herself summoned. This puts the two of them in symbiotic relationship : she maintains his existence with her TATARI powers while he supplies her with prana she needs to survive.

White Len and Len have a cameo appearance in second Kara no Kyoukai movie, where white and black cat plushies resembling them are shown while Ryougi Shiki explains to Kokutou Mikiya her split personality.
