Humbert Zizek

Humbert Zizek (ウンベール・ジーゼック) (alternatively spelled as Wanbell Jezeku) is a swordsman-in-training in the Norlangarth Empire's Independent Master Sword Academy. He's a 4th Class Noble Raios Antinous's follower and only friend.

Appearance
He has gray hair, always plastered in oil. During his first year in the Sword Academy he uses the same gray uniform as all the others, but in his second year, upon becoming an elite swordsman, he uses a pale yellow custom made uniform.

Alicization Running
He appears in the cafeteria sitting besides Raios Antionous, when Kirito and Eugeo sit near them. They raise their voice, emitting commentaries to enrage them.

He accompanies Raios to destroy the flowers that Kirito was cultivating, and mocks in Kirito's face when he comes to check up on his flowers. Days later Humbert becomes speechless when he sees Kirito giving the same flowers in perfect state to Solterina Celulute.

Alicization Turning
After seeing Kirito handing one of the flowers they destroyed to Solterina, he decides not to mess with him anymore and instead directs all his insults and mockery towards Eugeo.

When Eugeo comes to practice in the arena, Humbert is already practicing with Raios there. After teasing Eugeo and inviting him to duel them, they are surprised that he accepts to duel with Humbert. During the battle Eugeo makes him stumble, and, while he was recovering, Raios stops the duel and declares a draw. Although he didn't agree with this decision, he followed Raios orders and left the arena.

After losing against Eugeo he makes his valet enter the bathroom with him to give him massages and makes her strip to her underwear with the excuse that it's for her not to drench her uniform. Days later Eugeo and Kirito visit him at his and Raios room to ask him to stop mistreating Frenica. He plays dumb and acts as if he hasn't doing anything wrong, provoking Eugeo to comment how unproper it is to ask one's valet to undress and giving the two nobles the pretext to mock Eugeo for undressing in front of his mentor, Golgosso Valto, many times himself (though this was done so that Valto could confirm how his valet's muscles were doing and the training the boy lacked).

Another day he is visited by Ronie and Teiza in his and Raios' room and, as before, he plays dumb and this enrages the two girls to the point that they offend him and Raios, which was what they were expecting the girls to do. Using this offense as an excuse, the upper class noblemen make use of their right as higher nobles to judge lower nobles and apply punishment to the girls by raping them. He waits for Eugeo to arrive and orders him to watch as they "punish" Ronie and Teiza. When Eugeo, after building up the will power to break the rules, attacks them and cuts his arm, he tries to stop the bleeding by using the ropes that the girls were tied with, but is unable to act coherently due to shock. When Raios dies, he runs through the dormitory screaming for help and that Kirito and Eugeo were murderers.

Skills
Like Raios, he has been trained in the High Norlangarth (also known as High Norkia) sword style, which focuses on taking down the opponent with one hit.
