Mainichi HAPPY, lalala anata ga utau yo
Ganbare shiawase wa, aruite konaize

Shounen wa mukashi mukashi, iruka no sei naka ni
Yume wo daite, tobi notta
Genjitsu wo, zasetsu wo, nando mo kurikaeshi
Kigatsukeba tsukare kitte ita

Boro boro ni naru made, seken wo samayoi
Yagate me no mae ni, tairiku ga hirogaru

Mainichi HAPPY, lalala anata ga utaeba
Ganbare shiawase wa, aruite konaize

Umai hanashi ga, tsuzuku wakeganai
Kibou no hana, shioreteiku
Koukai wa shitakunai, dakara mou ichido
Yume no shima wo mezasu no sa

Gyakukire shisou na, DESK no kage kara
Te maneki shiteiru anata wo mitsuketa

Mainichi HAPPY, lalala anata ga utau yo
Ganbare shiawase wa, aruite konaize
Mainichi HAPPY, lalala anata ga utaeba
Ganbare shiawase wa, aruite konaize

Sui mo amai mo, kamiageta hito de sae
Naemi ga mattaku, nai wake janai daro
Yume no SCENARIO wa mada mada tsuzukuze
Gamushara OK? EVERYBODY ROCK N ROLL!
GUITAR!

Mainichi HAPPY, lalala anata ga utau yo
Namida wa fuite nara, issho ni utaou

Mainichi HAPPY, lalala anata ga utau yo
Ganbare shiawase wa, aruite konaize
Mainichi HAPPY, lalala anata ga utaeba
Ganbare shiawase wa, aruite konaize
Aruite konaize
Aruite ikouze

OH YEAH ganbare?
