Tsuna receives a letter. Inside the letter, there is a photo of someone wearing sunglasses and a note that reads “Try and catch me.” I-Pin sees the photo and is in shock. Reborn says that the person in the photo is I-Pin’s master, Fon, the holder of the red pacifier of the Arcobaleno. I-Pin wants to help Tsuna, but cannot help but is clearly hesitant to capture someone to whom he pledged his loyalty. Perceiving that I-Pin felt that way, Tsuna takes off by himself for the test. The test with Fon is a game of tag. Will Tsuna be able to catch the swift Bushido master?
Cette fois-ci, c'est le test d'aptitude de leader qui est proposé à Tsuna et ses amis. Ils doivent attraper en un temps limité l'Arcobaleno spécialiste des arts martiaux et maître d'I-Pin : Fong.
Tsuna riceve una lettera al cui interno c'è la foto di un uomo con gli occhiali da sole e su cui c'è scritto: "prova a prendermi". Reborn spiega che quello è il maestro di I-pin, Fon e che è uno degli Arcobaleno.
接下来负责考验的阿尔柯巴雷诺，是一平的师父“风”。为了避免尴尬，阿纲并没有请一平帮忙，而是带着蓝波以及凑巧遇到的小春接受风的考验。考验的内容是捉迷藏，然而面对身手矫健的风，阿纲等人简直是束手无策。
Comienza la prueba de liderazgo del arcobaleno Fon. En esta prueba participan Lambo, Haru, I-pin y Tsuna. Logran pasar esta prueba gracias al puño de gyoza de I-pin.
