For all you people wanting to smell Yamada's gi: That wasn't Yamada's BO, so have fun smelling dude sweat! It just wasn't washed properly before getting put in storage. At the end, Ichikawa was just trying to explain why Yamada didn't want to partner up with anybody, but his chubby chaser friend, Kanzaki misunderstood and thought that Ichikawa wanted to pair up with Yamada to get a whiff of her fragrance.
