Krilin vs. Demon Junior (クリリン対マジュニア, Kuririn Tai Ma Junia; lit. "Krillin vs. Demon Junior") is one hundred seventy-second chapter of Dragon Ball manga. The chapter's anime counterpart is the second half of the episode "Anonymous Proposal".
The chapter begins just as the fight between Kuririn and Piccolo. Krilin notices Piccolo's overconfidence in his power, and immediately warns him he will be fighting all out. Kuririn starts the battle by firing the Double Tsuihikidan at Piccolo. Piccolo easily dodges, flying in the air. Krillin then bends the beams upward at Piccolo, however, Piccolo manages to blow up both beams from a safe distance with his Eye Lasers. As Piccolo was blowing up the Double Tsuihikidan with Eye Lasers. Krillin uses that time to jump towards Piccolo, immediately punching him while Piccolo is distracted by the Double Tsuihikidan.
Piccolo admits Krilin is more impressive than he first thought and decides to get serious during their fight. The two fighters then partook in some close range combat, exchanging rapid punches. Then end result shows Piccolo with the upper hand as he kicks Krilin far back. It seems the fight is over, as Piccolo kicked him a good enough distance to knock him out of bounds. But it is then seen that Kuririn mastered Buku-Jutsu. Goku and Tien Shinhan are amazed at Kuririn's progress.
Piccolo once again admits he underestimated Krilin, not for his Buku-Jutsu, but for his toughness and speed. Piccolo then deems Krilin a worthy fighter to see "A true demon's power." Goku warns Krilin not to underestimate Piccolo's power as he is not bluffing.
