In this free-to-play social game, the player is the protagonist who commands a group of agents (samurai generals) to exterminate UMA (supernatural demons). Their goal is to save central Japan from the UMA and defeat their leader, who is believed to be located in a barrier within Kyoto.
The main story is episodic. It is presented in cutscenes which occur by completely finishing stages within a location. An option to review completed cutscenes is available to all players for free. New episodes are gradually being added for each major update.
Players can complete side events or daily quests to build levels and gain equipment.
To fight UMA, the player must assemble a team of agents into a formation before selecting a stage to play. Formations are arranged on 3x3 square grids. Each horizontal and vertical row can be swiped to change the agents' attack position. Their positioning may affect an agent's attack or innate skill.
Agents have three major stats: Attack, Life (amount of health in battle), and Speed. The max stats for any card relies on their rarity (the number of stars listed on portrait). One star is the lowest, four stars is the rarest. Their stats can be strengthened by gaining experience, fusing them with reserve agents, or by giving them equipment.
Every agent can equip a weapon, armor and a modern day firearm. Weapon alters a character's Attack. Armor alters their maximum amount of Life; certain pieces of armor can alter Attack and Speed.
Leveling up an agent can unlock their passive special abilities. Special abilities can do things like increase the agent's resistance to attacks or increase their attack potential. The game automatically shows which level the agent needs to unlock their two starting special abilities. Players can replace any special ability they want. To do so, the player must sacrifice an agent to pass on their special ability to another agent.
There are four major agent classes with these universal innate battle skills:
- Warriors: Fighters who attack in the front row only. They often have damaging techniques. Rifle and machine gun users.
- Strategists: Magic attackers who can attack from the front or middle row. Can have damaging or stat boosting techniques. Heavy firearm users.
- Archers: Snipers who can attack from any row. Often have group attacks for their techniques. Machine gun users.
- Medics: Healers who attack in the front row, cast an attack and defense buff in the middle row, and heal in the back row. Techniques are usually supportive buffs or healing spells. Handgun users.
Class promotions are available at levels 30, 50, 70 and 90. Promoting an agent increases their base stats and may grant a new innate battle skill.
Players can get agents by winning battles or by drawing from the roulette. Paid roulettes tend to have better agents.
Battles are turn based. Players are timed to decide their attack formation for each turn. Only one row can be swiped in one direction at a time. The game will have agents attack automatically if the timer runs out. Speed decides who attacks first once the attack turn starts.
During battle, specially marked Technique Squares will appear on the formation grid. Agents will unleash their technique if they are on top of it. Techniques are unique to each agent. Some examples include multi-hitting attacks or attacks that deal status ailments to UMA.
If an agent has a modern firearm equipped, a bullet icon pops at the bottom right hand corner of their battle portrait. The numbers next to the bullet indicates the percentage of the weapon's readiness.
When it reaches 100, tap the bullet to have the agent fire their firearm at the start of the attack turn. Nearby agents will fire their firearm if they also reach 100. Players can charge the firearm by having the agent attack or take damage. Fighters and Strategists can charge their firearms faster by moving out of their attack or innate skill range.
Strong UMA will have group attacks. The range of these attacks appear as red markers on the formation, giving agents a chance to dodge it. These attacks often include stat ailments like poison, paralysis, silence (cancels techniques), or jammed (cancels firearms). Players can see how many turns each effect will last by the number next the effect icon.
UMA come in three major classes: Beast, Undead and Demons.
- Demons are weak to Strategists and Medics.
- Undead are weak to Warriors and Archers.
- Beast are strong against everything but there are special abilities that can work against them.
- The UMA bosses in the main story may come in the strongest God class. These UMA bosses are strong against everything and have high hit points.
Players have a limited number of turns to win each battle. Defeat occurs by going beyond the turn limit. Digital currency can be used to instantly continue with a fully restored party.
