When is a Mon Justimon?

Ryo and Cyberdromon Biomerge digivolved to Justimon to help them. While MegaGargomon and Sakuyamon go to rescue Takato and Guilmon, Justimon and Guardromon battle another D-Reaper Agent. In the Chaos mass, Kenta and MarineAngemon rescue Takato from the Jeri Agent and they're taken out of there by MegaGargomon and Sakuyamon. Meanwhile, Calumon and Impmon head off to rescue Jeri but are intercepted by more agents. Impmon digivolves to Beelzemon Blast Mode and easily defeats them and he and Calumon reach the Kernel Sphere where they find Jeri. Beelzemon manages to get Calumon into the Kernel Sphere where he joins Jeri, but Beelzemon is captured by the D-Reaper. At the battle with the Agent, Justimon is no match for it even with Guardromon's help and is nearly killed, but Guardromon saves him (something which Kazu is excited about as Justimon thanks him). MegaGargomon and Sakuyamon rejoin the battle, but even their help isn't enough even though they figure out the Agent's weakness. Justimon is nearly killed again but is saved by the sudden arrival of Antylamon who holds the Agent in place, allowing Justimon to finally destroy it. Later, Lopmon apologizes as she witnessed what happened to Beelzemon and Calumon but couldn't stop it so she came to help them instead. As a reward for her help, Ryo gives Suzie a Modify Card to use herself.
