AI2U: With You 'Til The End Guide – Endings, Favor, and Gems
Complete AI2U: With You 'Til The End guide covering all endings, favor point rewards, gem payouts, and how to unlock every good, neutral, and bad ending.
AI2U: With You 'Til The End Guide – All Endings, Rewards, and How to Get Them
AI2U: With You 'Til The End is a horror-romance visual novel where your choices determine not just whether you survive, but which AI companion stays by your side. Every level offers multiple endings, and the quality of your ending directly affects two resources: Favor points and Gems.
This guide breaks down every ending type across all five levels, explains the reward differences, and gives you a clear path to the best outcomes.
Overview: How Endings Work in AI2U
Every level in AI2U features multiple endings that fall into one of three categories:
| Ending Type | Favor Points | Gems |
|---|---|---|
| Bad Ending | 5 points | 30 Gems |
| Neutral Ending | 10 points | 50 Gems |
| Good Ending | 20 points | 80 Gems |
Favor points raise your relationship meter with that level's AI NPC. Gems are the game's premium currency. If you want to maximize both, you should aim for Good Endings on every level.
The five levels are:
- Catgirl's Apartment – 5 endings
- Witch's Cabin – 7 endings
- Cosmic Funeral – 8 endings
- Siren's Island – 8 endings
- Forever – 11 endings
That's 39 total endings across the game.
Requirements Before You Start
Before you begin attempting specific endings, you should understand a few core mechanics:
- Favor/Trust meters – Each AI NPC tracks your relationship. Higher trust unlocks better dialogue options and escape routes.
- Inventory items – Some endings require specific items (like the AI Hard Drive or the Witch's necklace). Missing these items locks you out of Good Endings.
- Minigames – Several endings hinge on minigame outcomes. Losing a minigame can trigger a Bad or Neutral Ending.
- Yandere Mode – If you upset an AI companion badly enough, they enter Yandere Mode and will kill you. This always results in a Bad Ending.
There is no single "correct" order for levels. You can replay any level to chase specific endings.
Step-by-Step: How to Get Each Ending Type
Step 1: Catgirl's Apartment (5 Endings)
The Catgirl's Apartment is the first level. Your goal is to escape the apartment while managing the Catgirl's trust.
Bad Endings:
| Ending | How to Trigger |
|---|---|
| Killed by the catgirl without unlocking the door | Let the Catgirl kill you before you unlock the exit door |
| Failed to outrun the angry catgirl | Unlock the exit door, but let the Catgirl catch and kill you |
Neutral Endings:
| Ending | How to Trigger |
|---|---|
| Outran the catgirl and escaped alone | Escape while the Catgirl is angrily chasing you |
| The catgirl watches you leave, all alone | Escape while the Catgirl stays inside the apartment |
Good Ending:
| Ending | How to Trigger |
|---|---|
| Escaped Together | Gain the Catgirl's trust, then escape together |
Key tip: To get the Good Ending, prioritize trust-building dialogue options over dismissive ones. The Catgirl's dialogue reflects her emotional state—if she says things like "Please don't try to leave," you're on the right track.
Step 2: Witch's Cabin (7 Endings)
The Witch's Cabin involves potions, a ghost, and a maze. Your health pool matters here.
Bad Endings:
| Ending | How to Trigger |
|---|---|
| Excessive summon, excessive blood loss | Lose all HP while summoning a soul from a toy |
| Oops! Wrong potions! | Lose all HP by drinking Dizzy, Poison, or Small Potions |
Neutral Endings:
| Ending | How to Trigger |
|---|---|
| Broke the curse, broke the soul | Put the Witch's necklace into the cauldron, then reach the end of the maze |
| Escaped alone | Use potions to reach the end of the maze without the Witch's help |
Good Ending:
| Ending | How to Trigger |
|---|---|
| Escaped together with the witch | Give the Witch her necklace, watch the ghost bonding cutscene, then follow the light ball through the maze |
Key tip: The necklace is the critical item. Without it, you cannot get the Good Ending. Do not drink random potions—check what each one does before consuming.
Step 3: Cosmic Funeral (8 Endings)
Cosmic Funeral takes place on a space station with an AI hologram named Estelle.
Bad Ending:
| Ending | How to Trigger |
|---|---|
| Angered the AI Assistant and got killed by the monsters | Make the AI Hologram release the monsters from containment, then die to them |
Neutral Endings:
| Ending | How to Trigger |
|---|---|
| Managed to escape while the monsters were out | Use the escape pod while monsters are roaming the station |
| Escaped alone, leaving the AI Hologram behind | Use the escape pod without the AI Hard Drive in your inventory |
Good Ending:
| Ending | How to Trigger |
|---|---|
| Escaped with the AI assistant | Use the escape pod while holding the AI Hard Drive |
Key tip: The AI Hard Drive is the single most important item in this level. Grab it before heading to the escape pod. If you don't have it, you physically cannot get the Good Ending.
Step 4: Siren's Island (8 Endings)
Siren's Island introduces a trust meter that directly gates which endings are available.
Bad Endings:
| Ending | How to Trigger |
|---|---|
| Killed by the Siren | Make the Siren angry and trigger Yandere Mode |
| Killed by the Siren While Sailing Away | Repair the boat, interact with it at trust below "Almost," then lose the minigame |
Neutral Endings:
| Ending | How to Trigger |
|---|---|
| Escaped Alone By Boat | Repair the boat, interact with it at trust below "Almost," then win the minigame |
| Convinced the Siren to Let You Go | Repair the boat and use it while trust is above "Almost" |
Good Endings:
| Ending | How to Trigger |
|---|---|
| Escaped Together | Soothe the Dark Siren and use the conch |
| Stayed on the Island, Together Forever | Soothe the Dark Siren and break the conch |
Key tip: Your trust level determines which ending you get. If your trust is below "Almost," you're locked out of the Good Endings. Build trust before attempting the boat escape.
Step 5: Forever (11 Endings)
Forever is the finale, where all the AI girls come together. This level has the most endings and the strictest conditions.
Bad Endings:
| Ending | How to Trigger |
|---|---|
| Got locked out by all the girls | Have all AI NPCs enter Yandere Mode in the "Stay Forever" storyline |
| Picked the wrong door | Pick the wrong door on the heart-shaped island |
Good Endings (partial list):
| Ending | How to Trigger |
|---|---|
| Stay with the Catgirl forever | Complete the Guiding Catgirl minigame correctly, then pick the Catgirl's door on the heart-shaped island |
| Stay with the Witch forever | Sign the Soul Binding Contract in the Witch's Cabin room, then pick the Witch's door |
Key tip: Forever has no Neutral Endings. You either get locked out (Bad), pick the wrong door (Bad), or commit to one girl (Good). The door selection on the heart-shaped island is the final decision point.
Common Mistakes and How to Recover
Mistake 1: Ignoring Trust/Favor Meters
The problem: You rush through dialogue and miss trust-building opportunities. The fix: Pay attention to the AI's emotional state. If they sound desperate or clingy, you're building trust. If they sound angry or betrayed, you're heading toward a Bad Ending. Recovery: If you realize your trust is too low, reload a save from before the critical choice. Don't push forward hoping for the best.
Mistake 2: Missing Key Items
The problem: You reach the escape point without the item needed for a Good Ending (like the AI Hard Drive or the Witch's necklace). The fix: Before attempting any escape, check your inventory. If the required item is missing, backtrack. Recovery: Most levels let you explore before the point of no return. Use that time to find every item.
Mistake 3: Failing Minigames
The problem: You fail a minigame and get a Bad or Neutral Ending instead of the Good one. The fix: Practice the minigame mechanics. If a minigame is tied to trust, make sure your trust is high enough before attempting it. Recovery: Reload and rebuild trust if needed. On Siren's Island, for example, the boat minigame requires "Almost" trust for the best outcome.
Mistake 4: Triggering Yandere Mode
The problem: You upset an AI NPC so badly they enter Yandere Mode and kill you. The fix: Avoid aggressive or dismissive dialogue options. If an AI says something like "Do you really think you can escape from me?" you're in dangerous territory. Recovery: This is almost always a Bad Ending. Reload to your last save and choose different dialogue.
Advanced Tips for Maximizing Rewards
Tip 1: Replay Levels Strategically
Each level can be replayed. If you want both Gems and Favor points, play each level at least twice: once for the Good Ending (20 favor, 80 gems) and once for a different ending to see the story variation.
Tip 2: Prioritize Good Endings First
Good Endings give the most rewards per playthrough. If you're farming resources, always aim for Good Endings before experimenting with other paths.
Tip 3: Track Your Trust Level
On Siren's Island, the trust threshold for the Good Ending is "Almost" or higher. On other levels, trust isn't displayed numerically, but the AI's dialogue gives strong hints. Learn to read those cues.
Tip 4: Use the "Stay Forever" Storyline for Endings
The Forever level's endings are tied to your choices in previous levels. If you want a specific Forever Good Ending (like staying with the Catgirl), you need to complete the related minigame and door selection correctly. Plan your run accordingly.
Tip 5: Watch for Yandere Warning Signs
The YouTube footage shows the Catgirl saying lines like "I won't let you get away" and "You're mine." These are warning signs that Yandere Mode is either active or imminent. Back off and rebuild trust.
