Child Emperor vs. Phoenix Man

Child Emperor vs. Phoenix Man is the battle between the S-class hero Child Emperor and the Demon-level monster Phoenix Man

Prologue
Child Emperor is seen traversing through the Monster Association headquarters. Then, a monster with a cleaver appears behind him, but before he can attack, he is shot and killed by the Mini Octotank No. 8, a device created by Child Emperor that detects carbon dioxide levels in the area. Then, Child Emperor enters a room, where a broken robot is seen on an operating table. The hero quickly realizes that it is Bofoi's sentry robot, taken aback that the monster Bofoi spoke of was strong enough to cause such extensive and remarks that he wouldn't want to run into such a powerful monster. Child Emperor decides to download the data inside the robot's processor to obtain full schematics of the headquarters that might say where the hostage is, as well as any dialogue between monsters that might yield vital information. As he is downloading said information, he notices the arrangement of parts on the operating table, confirming that there was an unsuccessful attempt at recreating the machine. He also notes that most of the parts on the table have been perfectly reconstructed, and wonders if there were experts in robotics working for the Monster Association. The data is finished downloading, and the hero is relieved to see the precise location of the hostage. At the same time, he feels infuriated that Bofoi had such extensive knowledge and refused to help. However, he knows there was no use getting worked up, and leaves the room to retrieve the hostage.

Battle
As Child Emperor leaves the room, he takes out a large lollipop to relieve the built-up stress, but when he looks up, he sees Phoenix Man in front of him, his Mini Octotank No. 8 broken underneath the monster's feet.
