Hello!
Today I will write about the event!
The event “Spiral Extraordinary” is for a limited time from February 13, 2026 to March 18, 2026.
About the story
Bluetail Eye and Asmodeus travel all over the world and are targeted by castaways.
The story begins with these two helping that person, who was supposed to be dead in the original Gurren Lagann story.
Also, a group of castaways led by Shinna are targeting Bluetail Eye. Please check the story for the reason.
In order to draw parts 1 to 4 in this collaboration, adult Simon and Nia will also appear.
And there is a change in the story of the fourth part of Gleragan.
Please check out this if story of Gleragan.
However, what will happen to the battle of Getter Emperor, in which Bluetail Eye and Asmodeus participated?
*For details, refer to “Getter Emperor: Last Day in the Universe” which can be viewed in flashback mode.
About limited time quest strategy
From the “Base” screen, enter the limited time quest screen by selecting “Departure” – “Collaboration” and complete the “Spiral Extraordinary” below.
Stages 1-1 to 1-8 are left to the NPCs, so you can easily complete them. However, you may lose 1-6, but you can beat it if you try a few times.
1-9 “Small Miracle” is difficult for some people because you have to fight in a team that you have formed.
If you can’t win, use your friends (select another player’s team from the “Select Friend” screen) and get help from strong players (which can be estimated by the amount of coins spent) to conquer the game.
Other than that, it is an event battle with fixed units, so the strategy is easy.
New Year Celebration
In this limited-time quest, you can obtain the exchange item “New Year’s Firecrackers”.
This is an item to be exchanged at the Fragment Exchange.
