Anya’s “waku waku!” might be the most quoted line in anime right now — but what does it actually mean, and is it real Japanese you could say out loud? I’m a Japanese teacher, and in this guide we’ll go through the most famous Spy x Family quotes in Japanese — Anya, Loid and Yor — with accurate original text, rōmaji and English. The best part: because Anya talks like a small child, her lines are some of the most genuinely usable Japanese in any anime.
Can-you-use-it legend: ◎ = natural everyday Japanese · △ = casual/childish, watch the context · ✗ = anime only, odd in real life.

Anya’s words: the most usable Japanese in anime
| Japanese | Rōmaji | English | Use it? |
|---|---|---|---|
| わくわく | Waku waku | (so excited) I can’t wait! | ◎ Real, everyday onomatopoeia |
| おなかすいた。 | Onaka suita. | I’m hungry. | ◎ Everyday essential |
| ピーナッツがすき。 | Pīnattsu ga suki. | I like peanuts. | ◎ ~がすき is a core pattern |
| すごい! | Sugoi! | Amazing! / Wow! | ◎ Used constantly |
| ちち・はは | Chichi / Haha | (my) father / mother | △ Humble form — see note |
Teacher’s note — why “waku waku” is real Japanese: わくわく (waku waku) is a genuine onomatopoeia for a heart bubbling with excitement — Japanese is full of these paired-sound words. Its cousin is どきどき (doki doki), the pounding-heart of nerves or a crush. Both are ◎ and used by adults every day: 明日が楽しみでわくわくする (“I’m so excited for tomorrow”). Anya isn’t speaking baby-talk here — she’s using the language exactly the way real Japanese people do.
The one to be careful with — ちち / はは: Anya calls her parents ちち (chichi) and はは (haha). These are the humble words you use when telling other people about your own father and mother — not what you’d normally call them to their face. A child would usually say パパ・ママ or お父さん・お母さん (otōsan / okāsan). It’s a lovely detail: Anya’s Japanese is charmingly a little too formal for her age. Learn the pair — ちち/はは (my own, humble) vs. お父さん/お母さん (polite, anyone’s) — and you’ve learned a real rule of Japanese politeness.
Loid, Yor & the family-mission vocabulary
| Japanese | Rōmaji | English | Use it? |
|---|---|---|---|
| 家族 | Kazoku | family | ◎ Essential word |
| おともだちできた? | O-tomodachi dekita? | Did you make a friend? | ◎ Warm, natural |
| 任務 | Ninmu | mission | ◎ Real word (formal/spy) |
| がんばります。 | Ganbarimasu. | I’ll do my best. | ◎ Everyday polite |
| いい子だ。 | Ii ko da. | Good kid. | ◎ Gentle praise |
Teacher’s note — the 家族 (kazoku) word family: The whole show is about building a 家族, and the kanji 家 (ka / ie) means “house / home.” You’ll meet it everywhere: 家 (ie, house), 家族 (kazoku, family), 作家 (sakka, author). Notice おともだちできた? too: できる (dekiru) here doesn’t mean “can” — it means “came into being / was made.” 友達ができた = “a friend was made (I made a friend).” That’s a pattern you’ll reuse forever: 時間ができた (“I got some free time”), 恋人ができた (“I got a partner”).
The spy word — 任務 (ninmu): Loid’s 任務, “mission,” is a real, slightly formal word (the everyday version is お仕事, o-shigoto, “work”). It’s ◎ but serious — you’d hear it from soldiers, agents and, well, spies. Perfect for a dramatic Operation Strix moment; a bit much for “I have to do the dishes.”
Anime Spy x Family Japanese vs. real Japanese

Here’s the good news for learners: Spy x Family is one of the friendliest anime to learn from. Anya’s lines are short, present-tense and full of the exact patterns beginners need — ~がすき (I like ~), ~できた (~ was made), おなかすいた (I’m hungry). Almost none of it is rough or rude. The only things to file away are her cutely over-formal ちち/はは and her habit of referring to herself by name (アーニャは…) instead of わたし — a very small-child speech pattern, adorable from a five-year-old, odd from a teenager.
Steal Anya’s vocabulary, drop the third-person and the humble ちち/はは, and you’re left with clean, usable everyday Japanese. The fastest way to lock it in? Say わくわく and おなかすいた to a real Japanese friend and watch them grin — those words are 100% real.

What does Anya’s “waku waku” mean?

Why does Anya say “chichi” and “haha”?
