Arisu Chishiya

Arisu Chishiya (アリスちしや, Chishiya Arisu) is a student in Korosensei's Class 3-E of Kunugigaoka Junior High School who had transferred to Class 3-E alongside Itona Horibe and was one of Nagisa's closest friends.

Appearance
Arisu is a decently tall, young woman with long light-blonde hair, pale skin, and blue eyes. She wears a green and white dress with a large red ribbon with a blue and silver jewel on the chest and a dark green, almost black, ribbon with diamonds in her hair. She also wears a bracelet on her left wrist, black and gray thigh high socks, and red toe cap Mary Janes.

In one of her official artworks, Arisu wears a golden dress and a white crown.

During her time in Class 1-A to 3-A, she wore the standard issued school uniform except with a brown vest over her white dress shirt. She also wore a brown hairband with a four-leaf clover on the right side of her hair, black thigh highs, and brown loafers. Her hair was also styled differently.

Personality
Arisu is a cheerful and polite girl with a great interest in Japanese culture. Being a foreigner and related to royalty, she takes a great interest in many rather ordinary things as well, such as cleaning and even the Japanese restrooms, due to not being familiar with them. She firmly wishes to be treated like a normal Japanese high school girl and her big goal is to have friends of her own age and status. Due to being a foreigner, she occasionally messes up figures of speech and has a tendency to use very outdated slang in an attempt to socialize with her fellow students. Furthermore, Arisu is fascinated with serial killers and the occult and has actually stated that she likes Friday the 13th, which makes some other students a bit creeped out. She was extremely close to Gakushu when she was in Class 1-A up to 3-A. Even when she was in Class 3-E, he would still often talk to her.

Arisu is very kind and thoughtful, and she cares deeply for her friends, being very protective to those she holds a deep connection to. She can also be rather physically affectionate towards her friends, as she glomps Yukiko Kanzaki during one scene in an OVA. Her very polite personality is well-demonstrated by the way she is shown to be kind and polite even towards Ren Sakakibara and the rest of The Big Five, despite not really liking neither of them. However, she does possess a more hostile side towards Shiro, due to his behavior towards her dear friend, Itona. While she is very friendly, Arisu's commands are rather assertive and captivate the undivided attention of everyone surrounding her. It is stated that whenever she commands people, they feel an instinctive need to bow and listen to her. However, Arisu can also suddenly curse a lot and shout out loud whenever she is very upset or in deep distress.

Because of her upbringing, Arisu can be rather naïve and her general behavior can make her appear a bit ditzy at times, but she is actually smart and capable of complex political analysis, and reveals in her Free Time Events that she has faced many dangerous and stressful situations due to her status being a royal, and she is even skilled and fearless in combat. As a representative and authority figure of her country, she feels she has a great responsibility and always tries to stay calm and not show any weakness, even during the killing game. However, one time she was studying with Gakushu, she allows her ordinary self to be shown as she admits to Gakushu that she is desperate to go home to her people while breaking down in tears. She firmly states that she does not fear death, but she also won't let herself be killed nor kill any of her friends. She has a rather pragmatic side, that is useful during her training. Although she still tries to help as much as she could in trials, her despising the fact that she has to "doubt" her friends usually becomes a priority, implying that she is very loyal to those she genuinely cares for. During the final trial, it's indicated that she feels deeply ashamed to commit any acts of killing because they would be considered disgraceful, and in general, she is shown to be deeply loyal to her country and always prioritizes her people and country over herself, even if it makes her unhappy inside.

Abilities
Intelligence: Arisu is one of the smartest characters in the series that she is able to maintain her high grades with only little effort. She is also shown to be very good at language and a mastermind in sorts of tricks. She is also able to see through other people's strategy and foresee their next attacks.

Infiltration: As an infiltration assassin, Arisu is considered second to none. She is able to charm/distract her way into her target's inner circles, penetrating the highest security and killing/trapping them when they are alone at point-blank range with little difficulty. Arisu often has to adopt different personalities in order to infiltrate into the various situations her missions put her through.

Kiss of Death: From Irina, Arisu has apparently gained the "Kiss of Death" technique, able to acquire several "Hits" off of others through indiscriminate French kisses. She was taught this technique by her teacher, Irina.

Planning: After her seduction techniques, this is considered to be one of Irina's greatest talents. She can elaborate detailed plans completely on her own, with backups for any complication that might arise, thus giving her targets little to no chance of survival.

Linguistics: Arisu is extremely skilled in conversational abilities, being fluent in 10 different languages. Through these skills combined with her infiltration abilities, she is able to extract information from her targets.

Martial Arts Competence/Weaponry Master: Being an assassin, Arisu shows considerable expertise with handling weapons such as firearms and melee weapons, apart of being able of setting up complex trigger traps when attempting to kill Korosensei. She also is shown to be skilled in martial arts but since she is an assassin and not a combatant, she is severely under-skilled when compared to more prominent fighters in the series, such as Karasuma.

Other Abilities: Arisu has been shown to be able to play the harp at a concert-performer level with ease while still being able to draw people's attention through minuscule body movements.
