Naru's place with 〜んち
Grammar Explanation: One's house with 〜んち

A lunchtime conversation about recent jewelry store robberies gives way to talk about jewelry and the kinds Usagi and her friends would like to own.
- うさぎ:
- 「なるちゃんちでっかい宝石店だよね。あたしルビーすきーっ♡ パールもいいなーっ」
- “Naru 's place is a huge jewelry store, isn't it? (Me, I like rubies. Pearls are also nice.)”
「なるちゃんのうち」 is contracted into 「なるちゃんち」.
Key Points
なるちゃんち is なるちゃんのうち
〜んち is a casual contraction of 〜のうち, meaning someone’s home or place.
The missing の is built into んち
Learners may look for a separate possession marker, but ちゃんち already contains the のうち relationship.
A fuller version would be なるちゃんのうち, but Usagi says it in a compressed casual form.
だよね asks for shared agreement
Usagi is not neutrally stating a fact; she expects her friends to agree that Naru’s place is a huge jewelry store.
