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.

「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
