Definitely one of the greatest songs ever.
I can’t stop listening to it. ahhhhh. So incredibly leet. Such great lyrics that match up with the story too! damn damn damn, Byousoku really was a sad ending wasn’t it?

Lyrics from Animelyrics:
Koreijou nani wo ushinaeba kokoro wa yurusareru no
Dore hodo no itami naraba mou ichido kimi ni aeru
One more time kisetsu yo utsurowanaide
One more time fuzake atta jikan yo

Kuichigau toki wa itsumo boku ga saki ni oreta ne
Wagamama na seikaku ga naosara itoshiku saseta
One more chance kioku ni ashi wo torarete
One more chance tsugi no basho wo erabenai

Itsudemo sagashite iru yo dokka ni kimi no sugata wo
Mukai no HOOMU rojiura no mado
Konna toko ni iru hazu mo nai no ni
Negai ga moshimo kanau nara ima sugu kimi no moto e
Dekinai koto wa mou nanimo nai
Subete kakete dakishimete miseru yo

Sabishisa magirasu dake nara
Dare demo ii hazu na no ni
Hoshi ga ochisou na yoru dakara
Jibun wo itsuwarenai
One more time kisetsu yo utsurowanaide
One more time fuzake atta jikan yo

Itsudemo sagashite iru yo dokka ni kimi no sugata wo
Kousaten demo yume no naka demo
Konna toko ni iru hazu mo nai no ni
Kiseki ga moshimo okoru nara ima sugu kimi ni misetai
Atarashii asa korekara no boku
Ienakatta suki to iu kotoba mo

Natsu no omoide ga mawaru fui ni kieta kodou

Itsudemo sagashite iru yo dokka ni kimi no sugata wo
Akegata no machi sakuragichou de
Konna toko ni kuru hazu mo nai no ni
Negai ga moshimo kanau nara ima sugu kimi no moto e
Dekinai koto wa mou nanimo nai
Subete kakete dakishimete miseru yo

Itsudemo sagashite iru yo dokka ni kimi no kakera wo
Tabisaki no mise shinbun no sumi
Konna toko ni aru hazu mo nai no ni
Kiseki ga moshimo okoru nara ima sugu kimi ni misetai
Atarashii asa kore kara no boku
Ienakatta suki to iu kotoba mo

Itsu demo sagashite shimau dokka ni kimi no egao wo
Kyuukou machi no fumikiri atari
Konna toko ni iru hazu mo nai no ni
Inochi ga kurikaesu naraba nandomo kimi no moto e
Hoshii mono nado mou nanimo nai
Kimi no hoka ni taisetsu na mono nado

There’s other live versions and stuff too. Here’s one sung by a girl named Aiko, and another version also by a girl, both are well sung, but I like the original the best.
