In the game, The World Ends With You, the info for Yen pins say that they can evolve. However, every Yen pin I've come across has been a mastered pin, which is locked out of Pin evolution.
How do I evolve a Yen pin? Is there a way to find unmastered Yen pins?
1 Answer
Unmastered Yen pins can be purchased from shops as Quest items once you have high enough relationship with the shopkeeper.
| Pin | Price | Area | Store |
|---|---|---|---|
| 1 Yen | 2x Rare Metal | Shibukyu Stationside | Sunshine Stationside |
| 5 Yen | 2x Rare Metal | Cadoi City | Mus Rattus III |
| 10 Yen | 4x Rare Metal | 104 Building | Mus Rattus I |
| 50 Yen | 4x Tektite | Shibukyu Stationside | KuraKura |
| 1,000 Yen | 6x Tektite | AMX | AMX |
| 5,000 Yen | 12x Rare Metal | Spain Hill | Mexican Dog |
The 1 Yen pin can evolve into a 5 Yen or 10 Yen pin depending on the PP it is leveled up with. Other pins will evolve from Battle PP.
