Poyomon dl

Ryuji Mishima come back to Net Cafe Hudie to give their team info for their newest mission: to infiltrate the Tokyo Metropolitan Police Server. The group come up with a plan to have Keisuke pretend to be a Poyomon with malware installed. Inside EDEN, Ryuji would lure Matayoshi while Keisuke would try to 'accidentally' touch the latter, which would copy the access rights of the detective's avatar to Erika and to be used later on by Keisuke. They ask Yu Nogi to pretend that Poyomon is his pet and access that server. They meet up with Matayoshi, but before Keisuke can touch him, Makiko Date steps in the way, noting Poyomon's cuteness and hugs him tightly to her chest, prompting Erika to call a Keisuke a "Perv". Matayoshi, Date and Ryuji take off to pursue a fugitive hacker and Keisuke follows them. After Ryuji and Keisuke defeat the hacker, they are still unable to gain Matayoshi's access, however Erika was able to copy the access rights of Date's account, which is sufficient for their next mission.
