=Conquest= In this event, the event story will progress by advancing the Conquest mode. Conquest is a base-control event in which the goal is to steal the tiles in the event area before occupying the entire area.

General Mechanics
There are 3 types of tiles in the Conquest battle area:
 * General Tile: Occupying the tile requires AP; no battle.
 * Battle Tile & Base Tile: Requires AP to enter battle and defeat the enemies in order to occupy the tile, 1 battle.

Once the Base Tile is occupied, players can Analyze the Tile by spending AP to obtain Multi-Dimensional Arithmetic Circuit, Dimensional Engine Accessories, and Space Chocolate Burger. In order to Occupy and Analyze, players are required to assign teams for Battle and Analyze. Players can obtain bonus effects such as Battle Buffs and Reward Bonuses by assigning students to the specified schools.

There are 2 additional system beside Occupy and Analyze.
 * Settlement: is a function where players can earn credits as a reward when the AP gauge (500) is maxed out. The amount of credits that can be earned increases as players occupy more tiles and upgrade up their base tile.
 * Supply Box: A supply box is hidden in each area, and finding it will reward players with Pyroxene.

Battle Mechanics

 * Occupying General Tile costs 10 AP.
 * Occupying Battle Tile costs 15 AP.
 * Occupying Base Tile costs 20 AP.
 * AP used to initiate a battle will be refunded if a player is defeated or gives up in a battle to occupy a Battle Tile or Base Tile.
 * Players must clear the battle with 3★ in order to Analyze on the Base Tile. If you clear the battle in 1★ or 2★, you can occupy the adjacent tiles but will not be able to analyze on the occupied Base Tile.

Analyze Mechanics

 * Players must assign students to an Analyze Team at each Base Tile.
 * Players can borrow Club & Friend students to assist in analyzing the Base Tile. There are no rental fees.
 * Players can use the same students assigned to the analyzing team in combat team, and vice versa.
 * AP cost to analyze varies depending on the area, so please refer to in-game for more information.

Other

 * Settlement gauge will not accumulate if players spend their AP outside of Conquest mode.
 * Reward for Supply Box, Settlement, and Event Mission can only be received during the Event period.
 * Players can upgrade their Base Tile twice. Upgrading the Base Tile will increase the credits amount for Settlement rewards. You can also get Eligma when the base tile levels up.
 * Upgrading the base tile requires 45 and X Multi-Dimensional Arithmetic Circuits for Levels 2 and 3.

=Corruption= Corruption is a new mechanic added to this event's conquest mode. There are two types of corruption: small-scale corruption and large-scale corruption.
 * Small-scale corruption will occur 3 times at a random base tile. Reset at 4:00AM (JST) every day.
 * Large-scale corruption will occur once a certain amount of time has passed and 4000 AP has been spent. The first time, it will corrupt all of the base tiles in Area 2, then Area 3, and finally Area 4.
 * There will be a text box on the left side of the screen indicating the timer and area it will corrupt.
 * A warning screen will flash onto the screen when it happens.

Corruption Mechanics

 * From the 2nd day, the occupied tiles may be corrupted and stolen by the enemy.
 * When a tile is corrupted, the credits amount will be reduced when collecting Settlement reward, and a penalty will be incurred that prevents Analyze, and the occupation of Base Tile.
 * In order to remove the penalty, players must perform a removal operation on the corrupted tiles and win the battle.
 * Removing the corruption will earn players Credits, Enhancement Materials, and Pyroxene.
 * Players can perform removal operations using either the Analyze team or the Combat team.
 * Analyze Team does not requires AP to remove the corruption, but players will not be able to change the team set before the corruption. If the team has an "assist," a separate rental fee will be incurred.
 * Combat Team requires AP to remove the corruption, but players can freely choose their team members. The same students from the analyze team can be used in the combat team.

=Conquest Tile= Upgrading the Base Tile to Level 3 cost "X" Multi-Dimensional Arithmetic Circuit and rewards 5 Eligma.

You can upgrade your Base Tile whenever you want, as all Areas have the same credit reward. There are a total of "X" Base Tile in this event, upgrading all of them to max will give players a total of "X" Eligma. There are a total of "X" Base Tile in this event, upgrading all of them to max will give players a total of "X" Eligma.

If you have occupied all of the General Tiles and Base Tiles and upgraded all the Base Tiles to lv.3, you can earn "X" Credits per Settlement gauge.

Analyze Reward
In this base control type event, players will need to organize teams based on specific schools rather than characters, unlike in other event, making it easier to get the max bonus without requiring specific characters. The Maximum Reward Bonus in each Base Tile is 120%.

Due to the tile-based map, it is impossible to pinpoint the tile's position. As such, there will only be the analyze reward in each Area and no Enemy details.

Bonus Effect:
 * Battle Team Damage Buff = 2 / 4 / 6 Unit — 50% / 100% / 150%
 * Analyze Reward Bonuses = 2 / 4 / 6 Unit — 40% / 80% / 120%
