Koiseyo!! Imouto Banchou

Kono omoi wa gomakasenai
Taisetsu na kimi he todoite

Donna fuu ni omotteru? Sunao ni kiketara
Kikitai demo kowai utsumuite shimau
Motto tsuyoku naritakute kimi wo mamoreru kurai
Demo doushite darou? Mune ga ZUKUN to shita

Itsu datte oikaketeta akogare no HIIROO wa
Ima watashi no kokoro wo DOKI DOKI saseru'n da

Nee chotto kore ga koi na no desu ka?
Kanjita koto no nai omoi
Somaru hoho urusai kurai no kodou wa
Kagami no mae de nando mo maegami wo CHEKKU suru nante
Atarashii watashi kimi wa kizuiteru kana

Kanashii toki tsubuyaita kotoba no o-mamori
Namida koraete kimi to shita yakusoku
Daiji ni shita "yasashisa" to migaki tsuzuketa "tsuyosa"
Na no ni doushite darou? Tameiki ga dechau no

"Donna toki mo mamoru kara" kimi ga iu hitokoto de
Naki sou ni natte shimau kore wa "yowasa" desu ka?

Nee chotto kore wa koi na no desu ka?

Nee kitto kore ga koi na no desu ne?
Kanjita koto no nai omoi
Somaru hoho urusai kurai no kodou wa
Kagami no mae de nando mo kawaiku naare to negau no
Hontou no watashi kimi dake ni misetai na

Onaji keshiki wo mite onaji egao ni narou
