Killer Six Elements (chapter)

is chapter 190 of the Beelzebub manga.

Summary
Word about Oga's and Nasu's upcoming fight quickly reaches across the entire school. Two freshman students, Ebian Ichikawa and Kankurō Akahoshi, plus their respective gangs, are irritated that Nasu has already made his move against Oga. Both of their gangs head out to confront Oga themselves.

In one of the school hallways, several delinquents are surprised to see that Oga is there. Nasu, however, is excited and he goes over to introduce himself. He reveals that he is the one who marked over Oga's Zebul Spell tattoo earlier. Moreover, he felt very tired after experiencing Oga's "finisher" punch; upon that comment, Baby Beel draws short whisker markings on both of Nasu's cheeks. Oga grants Nasu a free punch for earlier and is subsequently sent flying towards the ceiling, effectively being buried in the concrete. The sight astonishes those around them. Natsume is particularly worried about Nasu's strength and remarks that the "Six Upstarts" have now risen.

Elsewhere, Nene informs several members of the Red Tail about the "Six Upstarts" in Ishiyama, who are all freshman students either ranked into the "Three Kings" or "Three Beasts". Ichikawa and Akahoshi are among the "Three Kings" while Nasu is ranked as one of the "Three Beasts".

Moreover, former members of the Red Tail have been transferred over to Mahō High School where, under the leader Ringo Hōjō, they have begun calling themselves the "New World Red Tail". Aoi has already encountered Ringo Hōjō and the "New World Red Tail", who are curious to know why she is not dressed as the proper leader of her former affiliation. In addition, it appears as though Aoi has already been aware of what former Red Tail members have been doing in her absence as a leader.

Nasu tauntingly asks whether the buried Oga can hear him. As he does so, both gangs from Sabatō High School and Hiaburi High School arrive in the hallways, ready to claim the title as strongest in Ishiyama; such a meeting results in a heated atmosphere between the "Kings" and "Beast". However, Oga silences them all when he tells them, from the concrete ceiling, that he will beat up all of them, regardless of who they really are.
