キミがいなくちゃっ！ はじまらないも～ん！！！！！

アドリブな毎日を　キミと過ごすトキメキ 春夏秋冬それぞれに胸が キュン！と跳ねだす “もっと”愛をつめて “ぎゅっと”ハグで歌おう♪ ぽっかぽかソングに　包まれて　うれしいな！

かけがえのないみんなでつくる　このカタチは ひとりだって(ハッピー！) 欠けちゃダメだ！(ハッピー！) キミがいなくちゃっ！！

きずなキラキラ　ボクらをつないで ちょうちょ結びで飛んでく～！ 向かう場所は　きっとハッピーだっ♪ (にっぱにっぱ！) えがおの花びら (にっぱにっぱ！) 世界へ舞いあがれ！ ハッピー！ラッキー！スマイル！イエーイ！！

はちゃめちゃな毎日も　キミがしあわせを呼ぶ 朝昼夜も1分1秒でも一緒にいたいっ！ “そっと”夢にふれて “もっと”ハートで踊ろう♪ あっつあつボイスで　願い事　唱えるね！

かけがえのないみんなで笑う　この時間は ひとりだって(ラッキー！) 欠けちゃダメだ！(ラッキー！) キミがいなくちゃっ！！

いのちピカピカ　ボクらのチカラで 運命は輝きだす～！ 出会う日々は　きっとラッキーだっ♪ (にっぱにっぱ！) えがおのくす玉 (にっぱにっぱ！) 世界へプレゼント！ ハッピー！ラッキー！スマイル！イエーイ！！

かけがえのないみんなで願う　あの未来は ひとりだって(ハッピー！) 欠けちゃダメだ！(ハッピー！) キミがいなくちゃっ！！

きずなキラキラ　ボクらをつないで ちょうちょ結びで飛んでく～！ 向かう場所は　きっとハッピーだっ♪ (にっぱにっぱ！) えがおの花びら (にっぱにっぱ！) 世界へ舞いあがれ！ ハッピー！ラッキー！スマイル！イエーイ！！

You've got to be here! Or else we can't start!!!!!

Spending every ad lib day with you is heart-throbbing Spring, summer, autumn, and winter; each season my heart Squeezes and goes leaping! Pack in more love Tightly hug and sing♪ It's delightful to be wrapped up in a warm song!

This shape that we make with every dear one Cannot have even (Happy!) One person missing! (Happy!) You've got to be here!!

The bonds glitter as they connect us Flying around in butterfly loops~! The place we're going to is sure to be happy♪ (Nippa nippa!) The petals of our smiles (Nippa nippa!) Flit up towards the world! Happy! Lucky! Smile! Yay!!

You call every preposterous day a happiness Morning, noon, and evening; each minute and second I want to be with you! Gently wave your dream Dance with your heart more♪ Chant your wishes in a passionate voice!

These times when we laugh with every dear one Cannot have even (Lucky!) One person missing! (Lucky!) You've got to be here!!

Our lives sparkle with our strength Our destiny will be radiant~! Each day we meet is sure to be lucky♪ (Nippa nippa!) The kusudama of our smiles (Nippa nippa!) Is a present to the world! Happy! Lucky! Smile! Yay!!

The future we wish for with every dear one Cannot have even (Happy!) One person missing! (Happy!) You've got to be here!!

The bonds glitter as they connect us Flying around in butterfly loops~! The place we're going to is sure to be happy♪ (Nippa nippa!) The petals of our smiles (Nippa nippa!) Flit up towards the world Happy! Lucky! Smile! Yay!!
