BUNNYBastion Romance Guide: How to Unlock All Relationships
Updated 2026-06-13

Introduction to Romance in BUNNYBastion
BUNNYBastion is primarily a fast-paced Roguelite tower defense game, but it also features a surprisingly deep romance system. After completing the first campaign run, you unlock the Sanctuary, a hub area where you can interact with various characters between battles. Building relationships with these characters unlocks unique dialogue, special perks for future runs, and alternate endings. This guide covers everything you need to know about the romance system, including how to increase affinity, which gifts to offer, and the requirements for each character's route.
How the Affinity System Works
Affinity is the core mechanic behind romance in BUNNYBastion. Each romanceable character has a hidden affinity score ranging from 0 to 100. You increase this score by:
- Speaking to them in the Sanctuary after each run (+5 affinity per conversation, once per run cycle)
- Giving them their favorite gifts (+15 affinity per gift, gifts are found in runs as rare loot)
- Completing their personal quests (+25 affinity, quests become available at affinity milestones)
- Choosing correct dialogue options during special events (+10 affinity)
Check the character's profile in the Sanctuary menu to see their current affinity level. You can also view a hint about their preferred gift type after reaching 30 affinity.
Affinity thresholds unlock new scenes and rewards:
| Affinity | Milestone | Reward |
|---|---|---|
| 0-20 | Acquaintance | Basic dialogue |
| 21-40 | Friend | Unlocks personal quest 1 |
| 41-60 | Close Friend | +1 perk slot in runs |
| 61-80 | Confidant | Unlocks personal quest 2 |
| 81-100 | Romance | Unique ending scene |

Step-by-Step Romance Process
Follow these steps to maximize your chances of completing a romance route:
Complete the First Campaign
Finish the initial story run to unlock the Sanctuary. This is required before any romance mechanics become available.
Choose Your Target Character
Focus on one character per playthrough to avoid splitting your resources. Check their gift preferences in the Sanctuary menu.
Collect Gifts During Runs
Prioritize rooms that contain your target's favorite gift type. For example, if romancing Lila, always enter Workshop rooms.
Complete Personal Quests
Once you reach 30 affinity, the first personal quest becomes available. Complete it as soon as possible for the +25 affinity boost.
Reach 100 Affinity
Continue gifting and conversing until you hit 100 affinity. The final romance scene triggers automatically at the start of your next Sanctuary visit.
You can only complete one romance route per save file. Choosing to romance another character will reset all affinity with the previous one. Make your choice carefully!
Rewards for Completing Romance Routes
Each romance route grants permanent account-wide bonuses that carry over to new playthroughs:
- Lila: "Engineer's Touch" perk - Towers have a 15% chance to repair themselves after each wave
- Rowan: "Scout's Insight" perk - Reveals the next room type on the map
- Mira: "Healer's Grace" perk - Start each run with a free healing item
- Kael: "Strategist's Edge" perk - +1 starting upgrade choice
These perks stack with other bonuses from the progression system. For more details on builds that complement these perks, check our character builds guide.
Frequently Asked Questions
Can I romance multiple characters in one playthrough? No, the game locks you into a single romance path once you reach 60 affinity with any character. You must start a new save file to pursue another route.
Do gifts carry over between runs? Yes, gifts are stored in your inventory and persist across runs until used. However, you can only hold a maximum of 5 gifts at a time.
Is there a time limit for romance? No, you can take as many runs as needed. The Sanctuary remains accessible indefinitely.
What happens if I give a disliked gift? Giving a disliked gift reduces affinity by 5 points. Avoid this unless you are intentionally trying to lower affinity to switch targets.
