石

• Reading: いし
• Romaji: ishi
• Kanji breakdown: 石 (stone) → used metaphorically for premium currency gems/crystals in gacha games
• Pronunciation: /i.ɕi/

Meaning

Premium currency 'gems' or 'crystals' in gacha games, used to pull for characters and items.

While technically meaning 'stone,' 石 has become universal gaming slang for whatever premium currency a gacha game uses — whether it's called gems, crystals, diamonds, or orbs. '石を貯める' (save gems) and '石を割る' (use gems for stamina) are core gacha vocabulary. The word reflects how deeply gacha mechanics have embedded themselves in Japanese gaming culture, creating their own economic language.

Examples

1. 配布の石だけで天井分貯まるまで我慢してる。 I'm holding out until I've saved enough free gems to hit pity.
2. 石を割ってスタミナ回復するかどうか悩む。 I'm torn on whether to use gems to refill my stamina or not.
3. 石が足りなくて推しのガチャ引けないのが辛すぎる。 Not having enough gems to pull on my favorite character's banner is just painful.
