About The Hundred Line Last Defense Academy

Project Extreme x Despair is here! "Kazutaka Kodaka" and "Kotaro Uchikoshi" comes a brand-new adventure game!

Takumi Sumino is a totally average teenager living in the Tokyo Residential Complex, a place where every day is much like the last and nothing bad ever happens. All that changes when freakish monsters attack the town and start wreaking havoc. A strange creature calling himself Sirei appears and offers Takumi the power to protect those he holds dear... All he has to do is stab himself in the chest!

The next thing he knows, Takumi is in Last Defense Academy, a school in the middle of nowhere surrounded by a wall of otherworldly flames. He and 14 other students have been drafted into the Special Defense Unit, a team tasked with keeping the school safe for the next 100 days. How much are they willing to sacrifice to take back their normal lives and save the world from the grotesque school invaders?

The curtain rises on 100 days of war and despair...

Extreme Despair-Filled Endings

Takumi's choices will decide his future, but there's no telling what kind of consequences these decisions might have...

Defensive Battles

When the invaders attack, it's up to you to protect the school in SRPG battles.

Use each student's unique Specialist Skills to turn the tide of battle in your favor!

Free Time & Exploration

Spend time with your teammates to deepen your bonds, or explore the wilderness and ruins outside the school.

You can even use the items you find to craft gifts and get even closer to your allies!

Most common FAQs when buying The Hundred Line Last Defense Academy for PC in digital format:

It is a key that will allow you to download the game The Hundred Line Last Defense Academy on your PC from official download platforms.
As of 23/07/2026, in United States, the best price we have found in our selection of online stores that include the key for The Hundred Line Last Defense Academy on PC is €23.51.
The Steam Key format is what we always recommend due to its ease of use and higher security compared to any other format.

The account format requires more complicated steps and is more prone to errors during activation.
The only issue we’ve encountered in 13 years is receiving a duplicate key that doesn’t work. In that case, simply contact the store where you bought The Hundred Line Last Defense Academy, and they will provide a new key. You can also contact us, and we’ll help you out.
Delivery times vary by store. For example, in the case of Instatgaming, Eneba, G2a, or Kinguin, delivery is usually instant or takes just a few minutes. These stores rarely delay game deliveries.

Other stores may take 30–40 minutes depending on game availability. On release days, delivery times may be slightly longer.

If you notice an unusually long delay, contact the store or us, and we’ll resolve it as quickly as possible.
At Gocdkeys, we only list the most well-known stores that have passed our quality checks. One of the most important factors is good customer support, and all listed stores offer it.
