Talk to Hiroko Sagisaka

Head to Shinjuku Park: Waterfall Plaza in Nishi-Shinjuku, then head to the southeastern corner of the area to find Hiroko standing next to a tree. Speak with her to learn about some ghosts that have been sighted in the area. She’ll want to start by traveling to the Community Forest.

When you regain control of the Agent, head down the side path on the north side to find a Digimon sitting at the end of the path. Speak with it to meet Guilmon. After choosing some of the dialogue options, Guilmon will head for the entrance to the sewers.
Chase the Digimon into the Shinjuku Underground

Enter the Shinjuku Underground Waterway to reach the South Block area. Head south along the path to spot Guilmon. Speak with it once more to trigger a fight against the Digimon.
