Bantan Sango Case Files

There have been some mysterious disappearances of Animals in Inazuma. The Bantan Sango Detective Agency will require the help of the Travelers to investigate and rescue the innocent creatures.

For this event, players will obtain a new gadget called Ubiquity Net. This gadget will allow travelers to capture animals and bring them to safety.

Players will equip with the Ubiquity Net, investigate suspicious locations, and avoid being detected by the Canine Bunshin, a Warrior Dog with the ability to replicate himself multiple times.

In this part of the event, players need to go stealth mode, Metal Gear Solid style. The Ubiquity can also activate particular objects to create distractions as fireworks and smoke machines or even stun the Canine Bunshin.

There are also animals captured in cages by Treasure Hoarders. Defeat all enemies, and you can catch the animals with the Ubiquity Net for further release.
