Iroi launches her banner on July 29, 2026, and with it comes one of the most talked-about outfit features in NTE Version 1.2: a swimsuit skin with a toggleable slipper option that the developers specifically added based on community feedback. This guide covers every confirmed Iroi outfit, how to obtain each one, and the best ways to spend your 999 Nights Buttons.
All Confirmed Iroi Outfits
| Outfit | Type | How to Get | Cost |
|---|---|---|---|
| Default (Healer Uniform) | Default | Obtain Iroi from her banner | Free |
| Swimsuit (Bikini) | Premium Skin | 999 Nights Button Shop (after 7/29) | ~1,500–2,000 Buttons (est.) |
| Exclusive Color Variant | Recolor | 999 Nights Button Shop (after 7/29) | ~500–800 Buttons (est.) |
Note: Exact Button costs will be confirmed when Iroi’s banner goes live on July 29. Prices above are estimates based on Shinku’s outfit pricing structure.
The Swimsuit Slipper Toggle — What Reddit Is Talking About
The most viral discovery this week: Iroi’s swimsuit skin includes a hidden toggle to show or hide her slippers. A Reddit post by u/Accelerator8964 (92 upvotes, 92 comments) revealed that players can switch between:
- Slippers ON — Iroi wears her signature bunny slippers with the swimsuit
- Slippers OFF — Iroi goes barefoot, showing her full barefoot look
This toggle was deliberately added by the NTE development team, making it one of the few outfits in the game with a customizable accessory option. The community reaction has been overwhelmingly positive, with top comments noting the developers’ attention to detail.
How to Toggle the Slippers
- Equip Iroi’s Swimsuit outfit from the Wardrobe menu
- Look for the Accessory Toggle option within the outfit customization panel
- Switch between “Slippers: Show” and “Slippers: Hide”
The toggle is only available on the Swimsuit skin — Iroi’s default outfit does not have this option.
999 Nights Button Shop: Iroi Outfits
Iroi’s outfits and exclusive color variants will become available in the 999 Nights Button Shop after her banner releases on July 29. The Button Shop is the primary way to spend the Buttons you earn from the 999 Nights mini-game activity.
How to Earn 999 Nights Buttons
The 999 Nights activity is a permanent feature in NTE where you play a tabletop RPG-style mini-game. Buttons are the currency earned by completing rounds:
| Activity | Buttons Earned |
|---|---|
| Complete a 999 Nights round | 50–200 Buttons |
| Daily login bonus | 20 Buttons |
| Weekly challenge completion | 100 Buttons |
| Special event multipliers | Varies |
Button Shop Priority Guide
With Iroi’s outfits arriving on July 29, here is how to prioritize your Button spending:
- Iroi Swimsuit — Highest demand item, purchase first if you want it
- Iroi Color Variants — Lower cost, good value for customization
- Furniture and Decoration items — Permanent stock, can wait
- Shinku outfits — Available since July 8, still in rotation
Iroi Default Outfit Details
Iroi’s default outfit reflects her role as a healer and her background in the Hethereau medical community. Key visual elements include:
- White and teal color scheme matching her Anima element
- Medical cross motif on her collar
- Her signature bunny slippers (present in default and swimsuit)
- Long flowing hair with teal gradient highlights
The default outfit is automatically unlocked when you obtain Iroi from her banner — no additional cost required.
Outfit Recoloring System
NTE Version 1.2 introduced the Outfit Recoloring system, which allows players to apply custom color palettes to certain outfits. Iroi’s outfits are compatible with this system:
- Access the Recoloring feature from the Wardrobe menu
- Select a compatible outfit and choose from available color presets
- Custom color presets can be purchased from the Fashion Shop using Riftcrystals
Should You Buy Iroi’s Swimsuit?
The swimsuit is a purely cosmetic purchase with no gameplay impact. Consider buying it if:
- You plan to use Iroi as your main healer long-term (she is expected to remain meta through Version 1.3)
- You enjoy the character’s design and want to support the developers
- You have sufficient 999 Nights Buttons saved up from the activity
If you are F2P and prioritizing resources, the default outfit is fully functional and there is no gameplay reason to purchase cosmetics.
Comparison: Shinku vs. Iroi Swimsuit
Both Shinku and Iroi received swimsuit skins in Version 1.2. Here is how they compare:
| Feature | Shinku Swimsuit | Iroi Swimsuit |
|---|---|---|
| Accessory Toggle | No | Yes (slippers) |
| Color Variants | 2 | 3 (estimated) |
| Shop Availability | Available now | Available July 29 |
| Community Reception | Positive | Very Positive |
Iroi’s swimsuit has generated more community discussion specifically because of the slipper toggle feature, which Shinku’s outfit lacks.
