Appearance
Shikki is an attractive and very tall, high schooler with long, straight brown hair pinned back in low pigtails, letting her fringe and bangs fall on her face. She has a fair complexion and very large, stern-looking, brown eyes. Her eyebrows are thicker than both Orihara's and Sakura's.

She typically wears her school uniform consisting of a white button up shirt (with tightly buttoned collar) and a navy blue skirt completed with a pair of sneakers and white soccer socks. She has also prominently been shown wearing her.

Personality
Shikki is very stern and passionate over judo as, having been defeated by Nagatoro easily she developed a deep respect for her, however when the girl abandoned her active career in the sport for years, she felt offended and got bitter to her, to the point of being angered at the sole idea that someone she considered a "quitter and returner" was simply welcomed into the judo club after having left, rudely commenting that getting hurt meant didn't even trying after injuring the girl's wrist in a match and despising Orihara for forgiving said attitude because of her attachment to the girl due to their past. Despite in those occasion appearing very harsh and spiteful however, Shikki is usually very taciturn and doesn't like to brag about her talent or archievement, as she state to consider "embarrassing" to be called the female judo club's "", she's also very compassionate and has an overall strong moral compass, refusing to report someone who have broken a rule by accident and even getting into trouble in order to help others.

In her daily life, Shikki is a very mature and level-headed girl as well and, after realizing to having done something wrong, she is quick to admit it and apologize for it, as well as being able - albeit with some reluctance - to change her opinion after understanding to having misjudged someone. Shikki is also a bit of a : after having understood her misdeed in hurting Nagatoro she became very caring about the girl well-being but dismissed it as trying to "be even" with her, when Senpai refused her help offer to sneak out of the female showers she reacted sadly but tried to play it cool, she's able to open up about her feelings only when alone with someone.

It is also strongly suggested that, despite her toughness among girls, Shikki is in contrast extremely awkward while interacting with boys, as she stammered and acted quite meek and shy while being scolded by Senpai and is visibly frustrated when stuck in a shower box with him. However, regardless of this, she has claimed not to mind a boy "seeing some [of hers] exposed skin" and is very at ease with her body. Despite this, she managed to talk smoothly with Senpai as time passes, eventually admitting to havin been impressed by his bravery.

A natural-born leader, Shikki is perfectly capable of quickly react and planning schemes or solutions while under pressure or in tense situations as well as making decision matter-of-factly regardless of how hard, distressing or embarrassing it might be for her.

Early life
Shikki was born in, , no information about her family or her home life are given. She seemingly became involved in judo at a young age and met Orihara and Nagatoro in her Junior High years, being utterly defeated by the latter during a championship and thus beginning to greatly respect the girl and her skills. However, after discovering Nagatoro had left the sport she became offended and start to resent her, calling the girl "a quitter who half-assed her life" an feeling very angered that she was welcomed back into the club.

After beginning to attend Kazehaya High School, she became a member of the judo club, making friend with two fellow clubmates, Fujimin and another girl, also she gained the reputation of being one of the club best member.

Trouble at the Judo club arc
One day, while practicing judo until late evening, Shikki, Fujimin and their third friend spoke badly about Nagatoro during their break time being, unbeknown for them, heard from Senpai. Later, Shikki challenged Nagatoro to a match and eventually hurt the latter's right arm while Senpai was watching. Despite having seriously hurted Nagatoro's wrist, Shikki spitefully mocked her saying that getting injuried so easily meant she "didn't even tried". Angered by this, Senpai stormed into the room and confronted Shikki - pleasently surprising Gamo-chan, Orihara and Nagatoro herself - telling her that what she had said was wrong due to Nagatoro actualy trying very hard everyday; to which the girl got surprisingly meeker and shy. Seeing their friend in trouble, the other two girls of Shikki's group accused Senpai of being a stalker and spying on them, however Nagatoro intervened saying that the boy always waited for her when she had judo practice; later the girl let herself be taken to the infirmary and discovered that her wrist was broken and would have needed two weeks in order to fully recover. The following morning, Shikki and her group approached Nagatoro and the boy to apologize.

Shower arc
Later that day, while having judo practice, Shikki and her gang saw Nagatoro having a run with Senpai in order to have some basic training and stare silently. Later, finishing her training, Shikki prepared to have a shower in the school gym's showers room while - unbeknown to her - Senpai was showering as well, the boy managed to hide back into his shower box right before she spotted him, however she walked right into his direction. Before taking a shower, Shikki discussed with her friends how, after the place was recently renewed, the positions of the male's and female's room were swapped, despite it was explained only a few hours before to the club members. Then, Fujimin detected "a boy's scent", informed her friends and angrily start looking for him with the other girl while Shikki managed to hear Nagatoro's voice and, thinking she was having a shower where Senpai was hidden, approached said box in order to ask about her well-being and - opening it - found the boy. Understanding the situation she decided to cover the boy, going as far as proposing to hid him with her body in order to allow his escape. eeling bad at the idea of being that close to a girl while both half-naked, Senpai politely refused, prompting her to promise she would have then hurried herself and her friends out of the showers. However, right at that moment more girls entered the shower room, forcing Shikki to enter the box with Senpai in order to keep him hidden and even open the shower head - thus starting showering - to avoid suspicion. Despite the awkwardness, of being stuck in the shower box - fully naked - with him, Shikki began to open up to Senpai confessing that his bravery when defending Nagatoro impressed her and, after the boy apologized for having yelled at her and explained that he did it simply because he knew how hard Nagatoro was trying, Shikki revealed about her past with the girl indirectly admitting that, deep down, she missed "the old Nagatoro". Hearing this from the other side of the shower Nagatoro was moved but Senpai ruined the moment noticing that Shikki's ass was rubbing against his; being unable to move back without opening the front door, the girl decided to turn the other side, ending up touching the boy's back with her bosom. Out of herself for the jealousy, Nagatoro jumped in the gap dividing the male and female shower boxes, squished herself into it and reached the other side, impressing Shikki with the flexibility she remembered and landing right in Senpai's arms after losing her grip. Later, Shikki exited the showers joining her friends and, before walking home with them, advising the pair to wait few more minutes before getting out of the showers. Then, Shikki went to the boys' changing room and took Nagatoro's clothes bringing them back to her.

Trivia

While the term refers to a group of four, and is often translated in English as the "Four " or the "Four Heavenly Kings", it is used for Shikki alone and it may be a pun on her name containing the word for "four" (四).
 * Her name might be a reference to in Saitama prefecture.
 * Perfectly in line with Nanashi's narrative style of showing both sides of social problems - like bullyng - Shikki's role in the story serves to show how even someone who is considered a bully, like Nagatoro, can in turn be bullied.
 * Like Orihara, Shikki and her friends seem to be Nagatoro's age and year level, though they all joined the judo club earlier, in their first year of high school. They are all aware of Nagatoro's judo champion past, her history with Orihara and her withdrawal from being active in the sport, all from her childhood.
 * She's the second character on the series whose name was revealed on her first appearance, the first being Rabi-chan.
 * However, while Rabi-chan wasn't called directly by name in her debut chapter - simply suggesting to be the girl in question while talking with the group - in Chapter 95 Shikki was called by name by one of her friends.
 * Due to Chapter 98 being titled after a line spoken by her, she is the sixth character after Nagatoro, Gamo-chan, the protagonist's sister, Sunomiya and Senpai to ever name a chapter.
