Toru (Tanaka Koki), a delinquent high schooler who spends his days fighting and consistently ranks last on academic tests, is finally called out by his mother, Reiko (Sato Eriko). She hires a stunningly handsome, supremely elegant super private tutor named Kishi Knight (Sawamura Rei ). Toru tries to chase him away with his usual nitpicking, but Kishi responds perfectly and gracefully, preparing textbooks for all subjects. Even his ridiculous answers are praised as "talent," leaving Toru completely perplexed! This is the beginning of a sweet lesson with the 1000% prince-like Kishi Knight (nicknamed Kishi Kishi).

Delinquent high schooler Toru (Tanaka Kouki) is fed up with adults who judge based on appearances. During his second lesson with tutor Kishi Knight (Sawamura Rei), Toru shows no motivation, lounging lazily on the bed, until Kishi surprises him with a quirky new teaching method: “sleeping together”! Caught off guard, Toru struggles to keep his cool. One day, on the way home, Kishi notices something about how Toru interacts with other kids. Focusing on what’s inside rather than outward looks, Kishi sincerely praises Toru’s good qualities, sparking small but real changes in him.

Yankee high schooler Toru (Koki Tanaka) desperately tries to resist getting swept up in Kishi Knight’s (Rei Sawamura) pace, but inevitably gets carried along by his flow. Even when Toru scores zero on a math mini‑test, Kishi Knight flashes his prince‑like smile and declares, “Mistakes are wonderful teaching tools.” He goes all out praising Toru as a “growth‑potential monster,” throwing him completely off balance. During English class, Kishi Knight suddenly brushes a gentle finger against Toru’s lips, offers him Okocha tea to help him relax, and treats him to a full course of gentlemanly behavior, leaving Toru’s heart racing from start to finish. P.S: Nobishiro Obake is a character from Japanese folklore, symbolizing growth and success.

Toru (Koki Tanaka), a delinquent high schooler, cuts short a fight with Tsuyoshi (Masaya Sakuragi), a delinquent from another school, and rushes home to make it in time for his lesson with his private tutor, Kishi Kishi (Rei Sawamura). Kishi Kishi praises Toru’s creative ateji like “Airabiyu” (“Love and Courage”) before beginning a lesson in classical Chinese. On another day, when Tsuyoshi mocks Kishi Kishi as “lame” for being a private tutor, Toru can’t hold back and ends up getting into another fight. As Kishi Kishi treats his injuries, he gently tells him there is a path to becoming stronger than winning through fighting. Motivated by the promise of a “reward for scoring 100,” Toru regains his determination to study once again.

「愛羅武勇」 is not a meaningful Japanese phrase. It’s a phonetic pun: each kanji is chosen only for its sound, not its meaning.

Applying the lessons taught by his tutor Kishi Knight (Rei Sawamura), delinquent high schooler Toru (Koki Tanaka) achieves over 50 points in every subject on his final exams. He begins to discover the joy of studying. As summer holidays begin, Tetsu happens upon a senior he'd admired. Finding the once-cool senior now rather lame, Toru seeks solace in Kishikishi – his ideal of a cool adult – and invites her out. Nervously excited at their first outing together, Toru watches as Kishikishi gazes up at the beautiful full moon on their way home and suddenly... N.B: 月が綺麗ですね (Tsuki ga Kirei Desu Ne) is a well‑known indirect way of saying ‘I love you.’ Responding ‘Yes, it is beautiful’ implies that the feeling is mutual.”

Yamasen asks Toru and his friends to volunteer at a children’s event, and their motivation skyrockets when they learn that Kishikishi will be attending. On the day of the festival, the group is confronted by delinquents from another school, but they avoid fighting and cleverly outmaneuver them. Assigned to play ghosts in the haunted house, Toru and Kishikishi work together to protect frightened kids. After the event, Kishikishi’s unexpected pickup by his butler raises a new mystery: who is he really? N.B: Waku Waku means Exciting in english

Toru (Koki Tanaka), a delinquent high school student, studies diligently under the guidance of his tutor Kishikishi (Rei Sawamura) and grows to the point where he achieves high marks in tests. His older brother Takeru (Yuto), who has returned home, also urges him on about the necessity of studying and to value Kishikishi, further fuelling Toru's motivation. Toru, a rebellious teenager grappling with his post-graduation path, finally discovers his dream. Rushing home to tell Kishikishi, he is ambushed from behind by rival delinquents Onizuka (Arasho) and Gonda (Nagata Takuro)...!

Toru (Koki Tanaka), who has been abducted by Onizuka (Shoma Arashi) and Gonda (Takuro Nagata), wakes up in an abandoned building. Remembering what he learned from Kishi Kishi (Rei Sawamura), he tries to reason with them, but is beaten one-sidedly. Just then, Kishi Kishi rushes in and confronts the two! Afterward, together with Kishi Kishi and his mother Reiko (Eriko Sato), Toru decides to spend a year as a ronin and retake the entrance exams next year, declaring that he will go to university. However, upon learning that his contract with Kishi Kishi is almost up, Toru becomes sentimental. Kishi tells him that this is no time for that and tries to push him forward, but…

Toru (Koki Tanaka), a delinquent high school student, declares during career counseling with Yamasen (Shuhei Handa) that he will take a gap year and become a teacher. Motivated by his new goal, he begins studying seriously, inspiring Yuki (Tasuku Miyazawa), Ryosuke (Sora Inoue), and Minoru (Keijiro Yagami) to join him. His final lesson with Kishikishi (Rei Sawamura) takes place on Christmas, where a perfect-score reward and a celebratory cake lead to an unexpected mishap. As time passes and graduation day arrives, Toru meets Kishikishi again and expresses his gratitude—then makes a promise not to see him again until he passes his university entrance exams.
