Appearance
Yukiko has long, straight black hair and light brown eyes. She is noted for being very beautiful by everyone in Class E as well as Ren Sakakibara of Class A, and is one of reasons that make her the most popular girl in Class E.

Personality
Kanzaki is a graceful and refined girl who's also very diligent and reliable. She's kind and calm with an elegant demeanor, but at the same time has a lot of backbone and isn't afraid to stand up for herself and will retain her usual smile while doing so.

History
Kanzaki comes from a conservative, strict, and what is implied to be a high-class family in which status was everything. Before dropping to Class E, Yukiko states that she was in Class A and due to the pressure and stress of her father who wanted her to be an ideal woman, she rebelled and started going to arcades and ignoring her studies which caused her grades to drop and ultimately landed her in Class E.

Synopsis
Yukiko was one of the first students to get a proper introduction after being introduced with the rest of her class in Chapter 1. She was first spotlighted in the Kyoto Arc when she was invited to join Group 4, Nagisa's group, for the trip by Sugino and when she and Kaede were kidnapped by high school thugs from another school. When Sugino invited her to join Nagisa's group, he referred to her as the class Madonna (or class belle in the OVA). Nagisa then noted her for her beauty, personality, and diligence and stated that there must not have been anyone who would object to being in a group with her.

When the class arrives in Kyoto, Kanzaki is searching for her notebook. When she can't find it, she says she must have dropped it, but unbeknownst to her it was pit-pocketed by some thug high schoolers she bumped into on the train. Afterwards the groups set out to do some assassination location scouting. Group 4 first drops by a convenient store which is the site of the 1867 Ryōma assasination and then Honnō-ji which was the ground of the assassination of Oda Nobunaga. After they visit those sites they then go to the Gion District under Kanzaki's recommendation. She says since the shops turn away first-time customers and tourists don't wander into the district aimlessly, they have to work around them making it the perfect place for an assassination. While the others compliment her on her point, some thug high schoolers walk up to them asking why they would come to a place that's perfect for abduction, alarming them. Karma is the first to step up and attacks the biggest thug there, reassuring Nagisa by saying if there aren't any witnesses then it's no problem. Right after he's hit on the back of his head with a pipe by the same thug who took Yukiko's diary then him and his friends proceed to kidnap Kayano and Kanzaki. When they're in the van, one guy tries to hit on Kayano who tells them they're ruining their trip to which the leader replies that that ruination is just fine then says Kanzaki should know what he's talking about. He shows her a picture of her, in a different appearance from her usual one, the previous summer in a game center back in Tokyo asking Kanzaki if that's her. He says that he planned to kidnap her and didn't expect for her to be a student at Kunugigaoka, but he "understood" in how people with high statuses want to be "ruined" and tells her that the "Ruination Sensei" will teach her absolutely everything on how to bring things to ruin.

When they reach an abandoned warehouse that's serving as the thugs' hideout, the leader says they have to wait for a few more of their friends to show up. While they're waiting, Kaede tells Yukiko that the picture before was a bit surprising and that someone as diligent and responsible as her had phases like that too. Yukiko tells her about her background and how her father was really strict and put status as the top priority. Wanting to get away from that style and to strip herself of the uniform that was her family's name, so she changed her appearance and went to play where no one knew her. She calls herself an idiot and says she doesn't know where she belongs anymore. The leader responds by saying she should become their comrade and mess up people who act like they're so elite referring to themselves as "missionaries of ruination." Kaede calls them awful and the leader smacks her, chokes her whilst telling that he's going to bring her down to their level for being so elite, then throws her onto the couch. It is then that Nagisa, Karma, Sugino, and Okuda show up to rescue Kayano and Kanzaki. The four, with the help of the guidebook and Korosensei, make short work of thugs and before taking out the rest, Korosensei tells them that they are not elite, but instead are the "leftovers" and suffer mass amounts of discrimination because of it, yet they continue to through it with a positive outlook and don't drag others into the mud like they do. He also says that school and status have nothing to do with it and like a fish, whether it lives in a clear stream or a water ditch as long as it continues to swim it will grow beautifully. He and the others then perform the signature "maintenance" and take out the rest of thugs with the guidebooks. After, they leave and Korosensei asks Kanzaki if she's alright, to she replies that is and thanks him.

Later that night when everyone is back at the hotel, Kanzaki is shown playing a danmaku, or bullet curtain game, which amazes everyone as she's playing as if on a pro level. She says she hid these abilities because they're frowned upon in their society, but then says that she thinks that she had been worrying too much about those sort of things and getting swept up with the crowd. Then she returns to the game with Kayano, with Nagisa noting the friendly atmosphere between them.
