Digimon Story Time Stranger: Underground Conflict Mission Breakdown

Access the Spiral Waterway
Begin by conversing with Lunamon, then locate Hagurumon through environmental clues. Progress through a compromised fence section and discover an accessible ventilation shaft. After regrouping with Lunamon, decide between investigating the In-Between Theater or advancing directly. The linear Spiral Waterway path leads to interactions with Little Bearmon near a stairwell – continue descending while engaging hostile Digimon obstructing progression.
Descend to the Waterway’s Depths




Upon reaching the waterway’s lowest tier, clear debris blocking the In-Between Theater entrance to secure supplies. Prepared fighters should proceed through the adjacent rift to confront Fugamon, Ogremon, and Hyogamon simultaneously. Prioritize eliminating low-health opponents first using combination techniques and special abilities for optimal combat efficiency. This decisive engagement concludes the Underground mission arc.
