Follow Lunamon to Hagurumon
After talking to Lunamon, follow it to a fence where Hagurumon is. Talk to Hagurumon.
2
Pass Through Fence
Pass through the hole in the fence and go to the open vent to the right, where you will talk to Lunamon.

After the cutscene with Lunamon, enter the vent. Alternatively, you may first visit the In-Between Theater at the back.

Find Little Bearmon
In Central Town: Spiral Waterway, follow the path until you reach the stairs where Little Bearmon is.
4
Descend Waterway
Proceed to the location of the objective marker. You will have to keep descending the waterway to eventually reach the objective at the lowest level. Fight hostile Digimon in your way.

Destroy Debris to Access In-Between Theater

6
Fight Fugamon, Ogremon, and Hyogamon
To the right of the rift to the In-Between Theater, you will enter an area with Fugamon, Ogremon, and Hyogamon standing on a platform. Defeat them to end the mission.

General Tips and Strategy

Defeat Fugamon First

Prioritize beating Fugamon first as it has the least number of HP of the three. Later, focus on defeating Hyogamon next and then Ogremon last.

Use Digimon That Target All Weaknesses

Boss Attribute Weakness Elemental Weakness
Fugamon BossFugamon Vaccine Water, Ice
Ogremon BossOgremon Fire, Earth
Hyogamon BossHyogamon Fire, Steel

Three of the bosses have their own elemental weaknesses but are mutually weak to Vaccine Digimon. Try to assemble a team of Vaccine Digimon that targets all their elemental weaknesses.

Use Cross Arts to Defeat Bosses Faster

Because there are three bosses, equip offensive Cross Arts like Cross Art: Strike. Otherwise, you may use Cross Arts that buff your team's damage, like Cross Art: Field.

Use Aegiomon's Stun Beat Blow Skill

Halfway through the battle, Aegiomon will learn the Stun Beat Blow skill. Capitalize on this skill to deal immense damage to the bosses while applying the Paralysis effect.
