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.
Resource management and crafting determine how quickly your power scales. This guide covers what to prioritize, where to farm, and how to avoid wasting resources on the wrong upgrades.
Crafting Priority List
The order you should invest resources:
| Priority | Target | Why |
|---|---|---|
| 1 | Primary equipment | Biggest damage increase per resource spent |
| 2 | Core build gear | Enables your build's key combinations |
| 3 | Defensive upgrades | Survivability for boss fights |
| 4 | Secondary equipment | Situational options for specific content |
| 5 | Consumables | Temporary boosts for hard content |

Upgrade Path
Early Game (School area to Desert area)
- Upgrade your starting equipment to functional level
- Craft basic defensive gear
- Save specialty materials, since you'll need them later
- Focus on Special Move once accessible
Mid Game (Forest area)
- Push Special Move to mid-level upgrades
- Start collecting materials for Hemoanima katana
- Craft situational consumables for boss fights
- Upgrade build-specific gear pieces
Late Game (Underground area to Coast area)
- Max out Hemoanima katana. This is your top priority
- Complete your build's core gear set
- Craft endgame consumables
- Optional: upgrade secondary equipment for variety
Crafting Mistakes to Avoid
- Spreading upgrades across multiple equipment: Focus one weapon to max before diversifying.
- Hoarding materials: Use them. The game provides enough if you farm efficiently.
- Upgrading the wrong gear: Check our builds guide before investing.
- Ignoring Forest area farming: This area has the best resource-to-time ratio in mid-game.
- Crafting consumables too early: Save specialty materials for late-game recipes.
Resource Efficiency Tips
- 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.
- Farm Forest area during mid-game for the best return on time
- Check the walkthrough to know when each resource becomes available
- Match your farming route to your build. Some classes farm faster in certain areas
