Description
Misao Otonashi, operating under the kaiju identity Noiseler, is a recurring character affiliated with the organization GIRLS. She mentors the entertainment class within the group. Her background includes forming a rock band with fellow kaiju girl Sachiko Dori (Zandrias), where she serves as lead guitarist; their planned concert was canceled after Miku Ushimaru (Miclas) sustained injuries from a Shadow Guts attack.

Physically, Misao has brown hair featuring a distinctive green stripe in her right bang and red eyes. She maintains a generally calm demeanor and listens to various music genres, favoring rock above others.

Her kaiju-derived abilities allow her to generate destructive shock waves through guitar playing, deploying them as offensive measures against enemies.

Key events involving her unfold during the timeline bridging the anime's first and second seasons. While walking home with Sachiko and Reika Shirogane (Windom), she witnesses a battle between Miko Innami (Alien Guts) and Miko's shadow-possessed duplicate in an alley. After Shadow Guts defeats Miko and turns to attack them, Misao prepares to transform into her kaiju form—only for Shadow Guts to retreat abruptly due to a sudden headache. Later, she participates in a collective battle alongside other kaiju girls against the Shadow General and her forces.

Her family name "Otonashi" (鳴無) references the title of *Ultraman 80* episode 7, "Operation Silent Tokyo" (東京サイレント作戦). She and Sachiko also perform a character song titled "Forgive me, kay?".
