Do you believe in reincarnation? I believe that everyone who fought demons and died for a peaceful world was reborn into a happier life.
 
Yoshiteru Agatsuma to Toko Agatsuma in Life Shining Across the Years

Yoshiteru Agatsuma ( (あが) (つま) (よし) (てる) Agatsuma Yoshiteru?) is the great-grandson of Zenitsu Agatsuma and Nezuko Kamado and the younger brother of Toko Agatsuma, who is a teenage student.[3]

Appearance[]

Yoshiteru shares a striking resemblance to Zenitsu Agatsuma, his great-grandfather, with black pelted hair and arrow shaped eyebrows. He is quite tall in comparison to his friends, as he is seen looming over the other students.

His school uniform consists of a light blue long sleeve shirt, accompanied by a white vest and black tie, as well as black slacks and brown shoes.[3]

Personality[]

Similar to his great-grandfather, Yoshiteru is somewhat exaggerated in regards to his reactions. When he was reading the book which explained the battle against Muzan Kibutsuji, he began crying over his ancestor's determination and willingness to risk their lives.[4]

Yoshiteru has also expressed the flirtatious tendencies of his ancestor as he was seen gawking at female students, as well as being threatened by the reincarnation of Obanai Iguro for staring at his wife's chest, whom was the reincarnation of Mitsuri Kanroji.[5]

Despite his flirtatious behavior, Yoshiteru is submissive to his sister and is somewhat afraid of her, saying that she's the opposite of quiet and polite. Upon hearing of her brother's actions, Yoshiteru immediately tries to defend himself in order to avoid his sister's scoldings.

Synopsis[]

Toko berates Yoshiteru

Toko berates Yoshiteru.

Yoshiteru discovers his great grandfather's record of the battle against Muzan in a storage unit. Upon reading the book, he gets overwhelmed with emotion and is promptly berated by his sister for not studying. As they walk to school, Yoshiteru asks Toko if she believes in reincarnations and expresses his beliefs that everyone who fought the Demons, was reincarnated into a happy life.

As his sister opened her phone to see the notification, she was immediately noticed with the latest news about an athlete named Tenma Uzui, who won a gold medal in gymnastics. Yoshiteru called Tenma a thug and rude, while Toko defended Tenma. Yoshiteru then snatches her phone and reads the article regarding Aoba Hashibira's discovery of the Blue Spider Lily. He becomes intrigued by her beauty and berates the public for criticizing her, but becomes furious when he discovers that Aoba was actually a man.[6]

Yoshiteru's envy towards Toko and Kanata

Yoshiteru's jealousy.

As they continue on their way to school, the siblings come across newborn twins which resemble Muichiro and Yuichiro as well as female students who resemble Shinobu and Kanae. Upon encountering Kanata Kamado, Yoshiteru begins to ominously curse him for flirting with his sister.[7]

The group continues on their way to school, and passes a daycare along the way. Yoshiteru notices the kindergarten teacher, who looks like Gyomei, and mentions his large body. When Toko asks Kanata if he wants to visit a nearby restaurant, he declines mentioning that they were previously threatened with a knife by the owner,—who looks like Obanai—due to Yoshiteru's excessive stares at his wife's—who looks like Mitsuri—chest.

Trivia[]

  • Yoshiteru's first name contains the Nanori of the kanji for "good" ( (よし) yoshi?) and the Kun'yomi for "illuminate" ( (てる) teru?).
  • He has gotten hit by a truck while protecting his sister. He managed to get saved without any large scars because of Toko applying first aid. He's a good guy inside, but he tends to be very unfair.[8]

Quotes[]

  • (To Toko Agatsuma) "Do you believe in reincarnation? I believe that everyone who fought demons and died for a peaceful world was reborn into a happier life."[9]
