Kill Blue

Thirteen rushes towards Noren. Meanwhile, Tenma and Eiji are engaged in an epic battle of soccer versus bomb golf. Tenma tries to put an end to his fight with Eiji using a technique he developed during practice! And after a fierce battle with Kazuma and Eiji, Noren, who had been unconscious, wakes up. What he sees reflected in his eyes is...

Under hypnosis, Noren falls in love with Juzo and aggressively pursues him. However, when Juzo gently rejects her, she attempts to jump off the roof. According to Kazuma, he had cast a hypnotic spell that would make her fall in love with the first person she sees when she wakes up, and a "heavy" one at that. Determined to break the spell, Juzo heads to the amusement park where he is meeting Kazuma, and ends up riding the Ferris wheel with Noren. Then, the two of them seem to be in a rather romantic mood...!?

Thirteen was enjoying a peaceful school life, but then Kazuma and Eiji transfer in, creating an unusual situation where four assassins have infiltrated the same middle school. Meanwhile, the Home Economics Club is holding a ramen-making championship. Thirteen, who is on the same team as Noren, saves a girl from being hit by a truck while investigating ramen. Who is this girl...?

Mai Otohime, who excels in all kinds of marine sports and possesses ocean knowledge that rivals that of experts, also aims for the Mitsuoka duel. However, Mai's target is Thirteen. Noren challenges her to a duel. Meanwhile, as Thirteen and his friends prepare for the duel, they have a three-way meeting. As each of them grapples with their own future, Thirteen also experiences a change of heart after his school life and encounters with his friends.
