Gaku is another one of Naota&#039;s classmates and close friends. In episode three, Marquis de Carabas, he plays the part of a mouse in the school play. Gaku also uses the word &quot;chu&quot; constantly, especially when referring to Haruko. This is a pun in Japanese, because &quot;chu&quot; is the Japanese onomatopoeia for both kissing and the sound a mouse makes. In the English version, &quot;chu&quot; is replaced with &quot;smooch&quot; to make more sense to English speaking audiences. He&#039;s somewhat hyper (compared to the bored composure of his friends) and is usually seen with Masashi. He is an encyclopedia of bizarre rumors and legends, many of which are sexual in nature

Naota is a detached sixth grader afflicted by the pangs of puberty. He's fooling around with his brother's ex-girlfriend when a crazed girl on a motor scooter runs him over, brains him with a bass guitar, and moves into his house. This pink-haired girl, Haruko - who claims she's an alien - hurls Naota into the middle of a mega-corporation's secret agenda. Oh, and now giant battling robots shoot from his skull. Mix in mind-bending animation and tunes that echo through your cerebellum to top off the trip that will have you falling hard for FLCL.

The older brother of [Stefano De Filippis](https://anilist.co/staff/147600).

The only production he has been participating in was FLCL, which is unconventional anime in many aspects but particularly in the seiyuu scoring. The children characters weren't voiced by seiyuus with "childish" voices, but by children of an corresponding age, like Miyajima Akira, who voiced Gaku character.

Naota is a normal Japanese 6th grade boy but when his older brother leaves for America to play baseball, his brother leaves his 17 year old girlfriend Mamimi behind. Mamimi is sending mixed signals and advances to Naota, and he doesn't know what to do about her. But to make matters worse, Naota's world is totally turned upside down when he is run over by a woman on a Vespa. During their first encounter, she hits him over the head with her guitar, which then causes a horn to grow out of his forehead. She calls herself "Haruko" and her presence changes Naota's life to even further insanity.
