General Gameplay Achievements
“Extreme” and “Despair”
Unlock all achievements.
This will take some doing, as it requires you to see every ending in the game, triggering everything along each route and making all kinds of upgrades to your team along the way.
Extermination Complete
Finish off an Enemy Commander.
After the battle on Day 007, you’ll have your first experience with transferring Commander powers to your teammates, defaulting to Hiruko this time and triggering the achievement. The next time this happens and every subsequent time throughout the game, the decision on who gets the power is yours to make, with the option to give it to almost any fighter on the field during that fight.
Listen to Me!!!
Successfully persuade someone.
Your first Persuasion Mission in the game will be with Tsubasa Kawana, teaching you how to make specialized teammate gifts and listen to their rationale in order to convince them to fight. Raise the persuasion gauge to 100% with Tsuabasa by giving her the Fashionable Sick Bag and talking to her about her grandpa’s workshop to claim this achievement.
Special Defense Unit
Take out 100 enemies.
You’ll trigger this naturally throughout the combat sequences in the main game, but it’s easiest done with low-level invaders that are easy to take out with teammates that hit multiple targets with a single AP.
Battle-Worn
Use a Special Attack 100 times.
Once you’ve got more than 100% Voltage during a battle, anyone on the field is able to use an individualized Special Attack that deals a large amount of damage in a large area. This does often afflict Stun, so you’ll need to weigh up your options carefully. They tend to be good for finishing waves during battles, since your team is restored between waves and the Stun effect will be removed by default. If it’s not the last turn but Nozomi is on the field, she’s able to remove Stun from any teammate as well without waiting for the wave to end.
Hemoanima Prodigy
Boost hemoanima 100 times.
After your team has filled the Voltage meter above 100% in battle, you’ll be able to do a variety of things for your team, not least of which is boosting their hemoanima to offer a variety of helpful boosts in combat, like giving them a small attack buff on their next attack or allowing them to take a second turn in battle without being bogged down by Fatigue. This will likely be a late-game achievement, unless you’re making a meal of each wave in battle or choosing to fight often while out on expeditions.
Welcome Back!
Return from an exploration.
Whether it’s a voluntary expedition beyond the Undying Flames during your Free Time or a story-based mission, coming back to school without fully draining Takumi’s HP and triggers this achievement. However, the longer you stay out exploring, the more treasures you’ll unlock and materials you’ll obtain, so the best way to keep yourself stocked up is to endure as much as you can before safely making it back to a checkpoint.
Irreplaceable Comrade
Reach max Bond Rank with someone.
Though your teammates help boost your grades along the way in the bulk of your first run of the game, you’ll have a chance to get to know them all more intimately later in the story, too. These achievements relate to the “dating sim” element of the game that unlocks toward the end of the first run.
Unbreakable Bonds
Reach max Bond Rank with everyone.
Mechanic
Upgrade a Class Weapon.
The first time you’re able to begin upgrading weapons is when the Training Room opens, allowing access to both the VR training machine and your first option for upgrading Class Weapons. This achievement will trigger the first time you upgrade someone’s abilities, which we’d advise doing when the Training Room first opens to give yourself a boost in all the coming battles.
Master Crafter
Upgrade someone’s Class Weapon to max level.
This will require quite a few resources and plenty of BP to achieve, but you’ll need to teach one of your teammates every skill in the Class Weapon upgrade list and have them max it out entirely. They’ll be much stronger for the effort, though, and you’ll have another achievement!
Researcher
Develop an Enhancement.
When the Bio Lab unlocks on Day 031, you’ll be able to make all kinds of items and modifications that help your team in battle. The first one you make triggers this achievement.
Scholar
Upgrade any Enhancement to max level.
The more you increase an Enhancement’s level, the more times you’ll be able to use it during battles. Like most other upgrades, it will require resources and BP to upgrade all the way, but keep checking back throughout the game to see what new items you can craft and max out.
Tinkerer
Develop a Trap.
With Kurara on the team and the Metal Shop open on Day 031, you’ll be able to develop all kinds of Traps that you can deploy during battle. You’ll have been given free experience with regular fences during the Day 028 defensive battle, but you’ll be able to make new kinds of fences as well as mines or bombs in the machine as well.
Developer
Upgrade a Trap to max level.
The more you’ve increased the level on any Trap, the longer it remains in battle as its stats increase. Stack up on resources to upgrade one all the way and trigger this achievement.
