Blood Blockade Battlefront - Kekkai Sensen Wiki

K.K. (K・K, K. K.) a lively and confident Libra member who sports an eye patch. She is very devoted to her two sons.


K.K is tall, thin woman with chin-length blonde hair & blue eyes, typically clad in a red trench-coat over a black crop-top, shorts & thigh-high high-heeled boots.


Typically cheerful, she cares deeply for her comrades & sons, whom she treasures above all else.

She seems to have a slight complex about her age and figure, and openly dislikes being around Steven, whom she refers to as 'Scarface'. She shares a much closer relationship to Klaus, whom she describes as a perfect gentleman and the leader of her organization. In fact, she worried and cried for Klaus after he was put at the brink of death and coughing blood from playing Prosfair for 99 hours in exchange for valuable information, and threatened to kill her subordinates if they couldn't use that information to good use as it nearly cost her friend his life. despite her confident and brave demeanor, she can be very emotional, such as being hurt over her son's declaration she was a bad mother because she couldn't make it to parent's night (having broken such promises multiple times due to her obligations with Libra) and crying over soap operas. She was also enthusiastic to learn her son had interest in a female classmate and was mutually interested in Leo's family drama in episode 11 season 2.

Possibly due to her strong relationships with her children she is also protective of children, as shown in episode 8 when she saved two children stuck in a car from being killed.

In season 2 episode 11, it is shown in her character card that she loves gossip shows, soap operas, women weeklies and gossip.


A Game Between Worlds.

K.K is first seen when she meets up with Klaus & Gilbert prior to the former's Prossfair game against the Don, having single-handedly defeated a small army of attackers.

Accompanying Klaus into the Don's demain, she is present when Ulchelko is defeated & realizes that the Don intended Klaus to sacrifice himself all along. Following the Game, she reveals the location of the Angel's Scale distributors to Libra whilst carrying a half-dead Klaus, tearfully threatening to kill the others if they allow the dealers to escape.

Bloodline Fever

A drunken K.K greets Zapp at Libra's party, promising not to attack him before voicing her displeasure at seeing the 'Cabal' of men gathered together, openly voicing her dislike of Steven.

When Leo unwittingly reveals that he saw a Vampire Elder in the Subway system, K.K voices her discomfort at Klaus' decision to bring in Blitz T. Abrahms before making herself scarce to avoid him.

Much to her displeasure, she is later partnered with Steven to stall the Elder & Tonio in the subway & is soundly beaten until Klaus arrives in time to seal them.
