Hello!

Today I will be writing about the event “Tengen Toppa Gurren Lagann”!

The event “Tengen Toppa Gurren Lagann” is for a limited time from February 13, 2026 to March 18, 2026.

Although this is a reprint collaboration, materials for super modification to Dimension Toppa Gurren Lagann are collected here, so that point is also included.

About the story

This collaboration is a reprint collaboration of “Tengen Toppa Gurren Lagann”.

Unfortunately, there is no story.

At that time, there were various theories about this, but it remains unclear even now. This is the first time he has appeared on Lee.

About limited time quest strategy

From the “Base” screen, select “Departure” – “Collaboration” to enter the following limited time quest screen.

You can choose between “Tengen Toppa” and “Challengers Hall”.

1) “Tengen Toppa”

Stages 1-1 to 1-5 are left to the NPCs, so you can easily complete them.

1-6 “Genuine Spiral Power” 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.

It would be easier to use sweeping when going around.

Collaboration limited items are required for limited time aircraft and super modification. Please don’t sell it by mistake.

2) “Challengers Hall”

You can challenge it by clearing “Tengen Toppa”. We recommend that you complete the entire challenge using almost the same specifications as the boss challenge. Materials can be collected.

About Dimensional Research Institute (T)

You can acquire aircraft restoration plans (there is a limit to the number of times, but you can obtain aircraft by consuming certain items) and pilots (Simon and Nia) by using the research points obtained by completing collaboration stages and expeditions.

From the “Base” screen, go to “Development” – “Dimensional Research Institute (T)” to proceed to the screen below.

Here you will get the aircraft by consuming collaboration limited items.

*We have prepared a table below to show how much material is required.

As for research points, by the time you have collected the required number of collaboration limited items, the conditions will have been met, so you don’t need to be too conscious about it.

Things to do throughout the event period

There are two main things you need to do: obtain collaboration limited items and join the pilot.

1) Obtain limited collaboration items

Collaboration limited items are required to acquire and super modify the aircraft.

Let’s go around until you get the amount of materials needed for the restoration plan and super modification at the Dimensional Research Institute (T). I’ll explain how to do this later.

2) Joining the pilot

Since there are differences in how to obtain the pilot, we will explain them separately.

How to join a pilot (Kamina, Lawgenom, Yoko)

You can obtain it using the following three standard methods.

Recruitment request (scout)

This is the method to scout by moving from the “coffee shop” screen to “request (scout)”.

Unlike Gacha, there is no ceiling (it is not a specification that you will definitely win if you play 100 times).

Soliciting at a coffee shop

This is a method that takes time but is easy to obtain.

Replacement of pilots at the coffee shop is optional. The free number of times will be added every three hours (but please note that you can only accumulate up to 5 times). Also, this includes one free exchange with no limit.

Replacing pilots is optional. Therefore, when the pilot you want to acquire arrives, you can use the option of increasing favorability by +5 with meals at 12:00 and 18:00 without replacing them.

The pilots will be replaced randomly, but the probability of them appearing during the event period is high (still 1%), so we will continue to do so.

In addition, if you tap the black cat that sometimes appears in the center right of the “Coffee Shop” screen and give it a favorability item (“Red Cape” for Kamina, “White Cloak” for Lordgenom, “Skull Hair Ornament” for Yoko), you can increase the probability of its next appearance by 17%.

If that’s not enough, you can repeat the change 39 times a day by consuming 20 Star Diamonds, so try it.

Then, when the pilot you are interested in comes, use coins, star diamonds, and presents (chocolate or chocolate bonbons) generously to increase his favorability.

Now, if your favorability rating rises to 60, you can invite them.

Use Heart Gift (Collaboration/T)

Purchase and obtain the paid item Heart Gift (Collaboration/T). This is the quickest method.

How to join a pilot (Simon, Nia)

If you reach 2000 research points, you can get Simon, and if you reach 4000 research points, you can get Nia at the Dimensional Research Institute (T).

There is no problem as you will be able to get it if you continue to collaborate steadily.

Required materials

1)Restoration plan

Number of items required for the aircraft that can be restored at Dimensional Research Institute (T)

2) Number of items required to unlock super modification recipe

* Separate materials (coins, superalloys, atomic cores) are required to modify the aircraft.

Collect materials

Describes the restoration plan and how to collect materials necessary for super remodeling.

1) When collecting materials for the Yoko tank restoration plan

Go around “Tengen Toppa” 1-3 “It’s up to you!!” or 1-4 “Good day, everyone.”

2) When collecting Gurren Lagann and Rasengan restoration plans and materials for super modification

Go around 1-6 “Genuine Spiral Power” of “Tengen Toppa” or 2-3 “Tengen Toppa Lv.90” of “Challengers Hall” (for those who are confident in their formation).

Conclusion

Because this is a reprint collaboration, those who have already completed the game will only have to collect materials for the super modification to Dimension Toppa Gurren Lagann.

However, since it was an early collaboration, this is the biggest chance for those who missed out on getting it.

I want you to do your best to conquer it.
