"Disastrous of Saiki K" Season 2 English Fandub 2

Kusuo Saiki is the main protagonist of "Saiki K" who has all kinds of psychic related abilities that almost nobody outside of his family are aware of. As the main character and the story is nearly driven by his narrative, Kusuo is a full, round character that changes over the course of the series. He tries heavily to not rely on his powers, wanting to achieve things for himself. As time progresses, he grows from not have any friends in his first year of high school, having no single thought of becoming close to anyone, to later thinking of himself as a friend of several of his classmates after much pestering from Riki, Shun, Kineshi, Kokomi, Chiyo, Reita, Aren and Mikoto. Due to a combination of his introverted nature and his subconscious ability to read minds, Kusuo holds little interest in social activities. Therefore, he typically spends his free time alone. 

Reita would do anything just to make girls fall for him. Like Kusuo, he was born with mysterious powers. Those powers being the abilities to see, talk to, and be possessed by ghosts. Reita uses these powers in selfish ways such as making ghosts do his bidding. However, he is shown to be very loyal, doing things as told usually, but usually messes these tasks up.

When Kokomi was first introduced, she was shown to be very conceited and a gold digger. As the most popular girl in school, and probably the whole world, she is highly sociable. She is a smooth talker, making her able to manipulate and persuade nearly everyone with her beauty and easily gets away from others with just simple excuses. Being flirted on and getting extreme reactions is normal for her, therefore when Saiki Kusuo was not startled or star struck by her beauty she was puzzled as to why. With this reasoning, along with her stubbornness and pride, she started to pursue after Kusuo until she fully falls for him.

Shun used to be shy in middle school and he had no friends at all. Once he began attending PK Academy, he started changing his personality with the plan of becoming adult-like. However, he instead caught "chuunibyou syndrome". He developed a split personality, where he acts as a confident chuunibyou at school and around his friends. However, when feeling hopeless or around his overbearing mother, he acts like a normal teenager. He is physically very weak and is terrible at sports and physical activity in general. He also cannot swim. Shun has a delusional mind and a wild imagination. He often tries to be cool and strong in front of Kusuo, but ends up humiliating himself more often than not, and is often quick to judge others.

Mikoto came to PK Academy after reading her own fortune and learning that her soulmate would be there. All she knew about him was that he had pink hair, crazy abilities, and the intials "S.K." After witnessing Saiki's powers, she learned that Saiki was probably the guy she was looking for, and she started following him to try to get close to him. This appears to have worked, as Saiki trusts her to help him, as seen when she pretended to be his girlfriend to get rid of Rifuta Imu's affections, and when she helped him stop the volcano from destroying Japan. Mikoto openly shows her psychic powers to everyone and became popular in her class because of them. She has a uninformed sense of justice and wants to use her powers for good and to help people, which she says separates herself from Kusuo. She will immediately and openly use her powers to help those who ask her, compared to Kusuo, who is more discreet and puts more thought into his actions. Mikoto is one of the few non-family members that knows of Kusuo's powers.
