S1·E30 Who Could the 6 Holy Knights Be?

Furuichi and Oga survey the school from the roof searching for emblems on people's shirts, and Azusa ends up tagging along in their search. Two students from St. Ishiyama are seen hassling two of Aoi's gang, causing Shiroyama to interject, telling them to leave. The two disgruntled students are offered a free punch by Shiroyama as compensation for breaking off their advance on the girls. They roll a large weight onto Shiroyama, hospitalizing him. Kanzaki bursts into the classroom the two boys are in later that day to get vengeance, only to be knocked out by Miki in one blow. Miki the invites the students of Ishiyama High to meet him on the roof after school. Himekawa, Natsume, Furuichi, Oga and Aoi all go to the roof after school, though Furuichi stays in hiding.
