Event Overview

The Mini Special Event offers the following content: Story, Quests, and Challenges. Clear quests to unlock the rest of the story.

■ Story

You must clear quests to progress through parts of the story.

Even if you are unable to reach the end of the story during the Mini Special Event period, please rest assured that it will be available to view as a Character Story after the event ends.

You can access Character Stories from Home > Story > Characters.

■ Quests

Deploy for quests by consuming Stamina.

By clearing a quest, you can proceed to the next one.

Quests have Combat Objectives. If you clear all Combat Objectives, you will be able to use the skip function on subsequent attempts.

Clear quests to obtain Interlude Notes, which can be used in the Event Gacha to exchange for various items.

■ Challenges

In Challenges, you can take on high-difficulty battles.

Stage effects will be active in Challenges. Be sure to make full use of them to secure yourself an advantage.

■ Missions

You can earn rewards by clearing various missions.

You can also earn Interlude Notes from mission rewards, which can be used in the Event Gacha.

■ Event Gacha

You can perform one pull in the Event Gacha by consuming 10 Interlude Notes to exchange for various items.

By adjusting the Pull Settings, you can exchange Interlude Notes for up to 100 pulls at once.

The Event Gacha contains up to 500 rewards. By meeting certain conditions, you can reset the rewards and earn them again.

For Lineups #1 to #4, you can reset the rewards after obtaining the key reward.

Resetting the rewards will switch the current lineup to the next one.

The key rewards for each lineup are as follows:

・Lineups #1–2: Dimensional Crystal x150

・Lineup #3: Home background "Calculated Choice"

・Lineup #4: Kaiju Core Material

For Lineup #5 and beyond, you can reset the rewards after obtaining all rewards in the current lineup.

*If you do not obtain the Home background from the Event Gacha, it will be available for exchange with Encounter Stones at Home > Shop > Encounter Stone after the event period ends.

If you already own the featured Home background, it will be converted into the same number of Encounter Stones required for the exchange.
