Dandadan , Chapter 169

Okarun swiftly runs through the school corridor, passing other students. Someone stops him.
Their teacher, Mr. Sanjome, stops Okarun and tells him it is dangerous to run. He asks if he discovers new secrets.
Okarun walks frantically while answering he discovered some secrets. Mr. Sanjome follows him to know more.
Mr. Sanjome keeps following Okarun while telling him about noise-cancelling waveforms. Okarun walks faster.
Mr. Sanjome explains and visualizes the synchronization of metronomes and bacteria.
Mr. Sanjome tells Okarun that a human's body comprises 10% cells and 90% bacteria. Okarun is impressed.
Okarun turns around to see Mr. Sanjome, who asks if he accepts defeat in the face of his knowledge. Okarun is shocked.
Okarun playsfully smiles while accepting his defeat and promises to tell him more knowledge one day. Mr. Sanjome is shocked!
Okarun playfully smiles while walking as he turns right. Mr. Sanjome stops following him and watches him as he goes.
Mr. Sanjome reveals a tiny knife and puts it back in his pocket. He turns around and walks alone down the hallway.
Meanwhile, tiny Momo tells Aira, Jiji, Vamola, Rin, and Sasaki about the eerie girl looking for her.
Aira lets tiny Momo climb into her uniform. Okarun arrives and asks tiny Momo about the attacker's distinguishing feature.
Tiny Momo further reveals the woman also told her to yield. Suddenly, Aira tells Okarun not to speak at her breast.
The gang gets crazy as Aira keeps flirting with Okarun about him looking at her bosoms. He wants Okarun to apologize.
Tiny Momo looks gloomy while listening to Aira's drama on Okarun. Aira holds Okarun's arms and tells him to be more direct.
Tiny Momo uses her power to throw a chair at Okarun. She argues with Aira. Rin leaves. The weird student is in the hallway.
The weird student walks past a door. Behind it, he hears someone telling her how to steal the opponent's abilities.
The person behind the door advises the weird girl on how to use her powers.
Suddenly, some tiny spirits with conical ears appear behind the girl! The tiny spirits emit some form of an aura.
