Denki Kaminarimon

is a Konohagakure Academy student, and the heir to the Kaminarimon Company.

Personality
Denki is a rather shy boy and he is not able to stand up for himself. Denki says that he wants to stand up to his father so he can study and become what he wants. His personality later changes when he is bitten by a shadowy figure which causes him to try to kill the gang of boys that were bullying him. Denki soon snaps out of it and helps Boruto Uzumaki bring an end to what he has caused. Denki becomes more confident in himself after the event when he joins the Academy.

Appearance
Denki is a bespectacled boy with dark eyes and black chin-length hair some of which he gathers in a top-knot, allowing the rest to fall around his face. He wears a blue suit with white trimmings, blue shorts and sandals. He is particularly small for his age, standing as the shortest of all the Academy students.

Abilities
Denki is quite an intelligent boy, showing enough skill with computers that he was able to hack the Academy's security systems.

Academy Arc
He was bullied by a group of students in an alley where Boruto passed by and helped him. The two immediately became friends and Denki was inspired by Boruto to act on his own and pursue what he wants causing the former to have an argument with his father where a certain unknown shadowy figure overpowered him and "partially" controlled him. On the way to the opening ceremony of the Academy, Boruto saw Denki and followed him. He learned that Denki was planning to get his revenge from his bullies which surprised Boruto. There, Boruto saw something on Denki and thought it was peculiar. Following on the events on the train, Boruto learned that Denki was trying to collide their already defected train with another train defect. Due to Boruto's words and pursuing, Denki seemed to become aware of what he was doing, just in time of collision Boruto managed to swing the switch to move the train out of another rail and before Boruto might fell Denki saved him together with the bullies. Boruto and Denki then approached the opening ceremony using the defected train causing it to hit with the Seventh Hokage's stone face. The next day, Denki made it to the academy and seem to be friends with Sarada Uchiha and Chōchō Akimichi.

Two weeks later, after Boruto's suspension ended and he finally joined the class, Denki greeted his new friend. Soon afterwards, Boruto performance in a practice run earned him second best in the class, which Denki congratulated Boruto on. Later, while trying to have lunch together in the class room, they got into a confrontation with the class' top student Iwabee Yuino. As the rebellious older student began speaking out on his views of strength being everything to ninja and Boruto represented the worst of the students being lazy, Denki stood up for his friend. He insisted that Boruto is as driven as anyone and wants to make a name for himself. Iwabee, annoyed at Denki talking back to him, grabbed him fiercely, to which Boruto came to Denki's aid. As two students began arguing about what it means to be shinobi, they decided to skip class to settle things in fight. Denki joined the rest of the class to watch the fight in a training arena. Ultimately, Boruto and Inojin Yamanaka's respective words resonated with Iwabee, ending the fight. Despite the pleasant ending, Denki and the rest of the class were fiercely scolded later by sensei Anko Mitarashi for skipping class.

During a class introducing students to summoning techniques, Boruto's continued antics to show off, Sarada scolded him on his foolishness. This sparked an argument between all the boys and girls. Later during their lunch break, Sarada began to fight with Boruto over who would get the last yakisoba bun. Shino appeared, insisting that they boys and girls settle things with a race challenge for a flag. The challenge quickly got heated. Denki used his computer skills to hack the Academy's security system but ultimately Denki was captured by the girls. In the end contest ended with the girls getting the flag. Despite their victory, the girls made peace with the boys after working together to save Chōchō from falling off the roof.

Later, the class gained a new transfer student from Otogakure named Mitsuki. Wanting the students to warm up to Mitsuki, Shino organised a welcoming party for the new student. When Shino's efforts for the party backfired with his insects, the class began to freak out, with Denki begging someone to make the insects go away, which Mitsuki did with his Wind Release: Breakthrough, causing even more damage to the Academy.

Trivia

 * Denki's name, when written as 電気, means "electricity". His last name, literally meaning "Lightning Gate", most likely comes from one of two gates locating in Asakusa, Tokyo, Japan.
