Too Kyo Games and Media.Vision released The Hundred Line -Last Defense Academy- on 24 April 2025 for Switch and PC, with Kazutaka Kodaka and Kotaro Uchikoshi writing and Aniplex publishing. Takumi Sumino is pulled out of the Tokyo Residential Complex into a school ringed by fire, where fifteen students form the Special Defense Unit and hold the building for 100 days against School Invaders. Story days alternate with grid based battles, and the choices you make across those days fork the run into 21 routes and just over 100 endings.
Picking the right build determines how your experience plays out. These builds are ranked by overall effectiveness, factoring in damage, survivability, gear requirements, and how well they scale into endgame. New to the game? Start with our beginner's guide first.

| Core Gear | Best available for your level | Maximizes build potential |
| Stat Priority | Balanced offensive and defensive stats | Optimal scaling |
| Key Mechanic | Shared AP pool with rollover | Each player phase gives the whole squad one pool of attack points rather than one action each, and the player team always moves first. |
How to Play Takumi Sumino

Cons:

A-Tier: Karua Kashimiya
Karua Kashimiya is a strong option in The Hundred Line -Last Defense Academy-.

| Core Gear | Best available for your level | Maximizes build potential |
| Stat Priority | Balanced offensive and defensive stats | Optimal scaling |
| Key Mechanic | Hemoanima Special Moves | Hemoanima is the blood drawn power the students fight with, and Takumi Sumino's takes the form of a katana with wide horizontal and vertical sweeps plus one armour piercing strike, on a movement range of roughly five to six tiles. |
How to Play Karua Kashimiya

| Core Gear | Best available for your level | Maximizes build potential |
| Stat Priority | Balanced offensive and defensive stats | Optimal scaling |

Pros:
- Strong in group/team content
- Straightforward gearing path
- Excels in its niche
Cons:
- Weaker solo performance
- Requires deep game knowledge
A-Tier: Eito Aotsuki
Eito Aotsuki is a specialized option in The Hundred Line -Last Defense Academy-.

Pros:
- Unique, rewarding playstyle
- Straightforward gearing path
- Excels in its niche
Cons:
- High skill floor, punishing when misplayed
- Requires deep game knowledge
Build Progression Path
- Start with Hiruko Shizuhara: the most forgiving option for learning the game
- Transition to Takumi Sumino once you understand core mechanics and have access to Hemoanima katana
- Keep a Karua Kashimiya setup for content that keeps killing you
- Try Eito Aotsuki for a fresh experience once you've mastered the basics
Follow our walkthrough for the optimal progression path through each area.
Gearing Tips
- Invest in your primary equipment first, since it gives the biggest power spike. See our weapons guide for rankings.
- AP is a squad resource, not a per unit one. Ending a turn with points left over is a legitimate strategy because the leftovers roll forward, and a banked turn followed by a five action turn beats two average turns almost every time.
- Voltage stops accumulating at 300 percent inside a battle. If the meter is sitting at the cap and you are saving for a better moment, you are throwing away everything the next three attacks generate.
- Don't spread upgrade resources across multiple builds until endgame
