Which chapter in prince of tennis is this?

I'm not sure if it's in the NEW PRINCE OF TENNIS or the original, but I wanted to know this chapter (http://princeoftennis.wikia.com/wiki/Seiichi_Yukimura#Prior_To_U-17_Camp) on the slide show where it shows 2 pictures it has Yukimura walking down stairs and finding out that his teammates drank Inui's juice. Does anyone know this chapter #?
