Requested by Alice, the lyrics don’t exactly suggest the characters whose themes this song is based off, if you ask me. I don’t know if there was a message somewhere (perhaps a tweet?) by the one of the artists explicitly saying who it’s about, or if the lyrics are completely generalized (not Touhou related), but, for the time being, Renko x Merry is a good assumption to make.

tsuki o meguru hoshi no kazu dake
watashi wa yume o miru
futari wa de au made no subete o sutete
doko made ikeru no?

For each star revolving around the moon
I have a dream
Throwing away everything until we meet,
how far can we go?

花びら舞い散る桜の下で
夜闇を照らした夢物語
いまから始めよう　もう一度だけ
見果てぬ　あの星掴むまで

hanabira mai chiru sakura no shita de
yo yami o terashita yume monogatari
ima kara hajimeyou mou ichido dake
mi hatenu ano hoshi tsukamu made

Under the cherry blossom tree with petals dancing down
is a story of a dream that lit up the dark night
Let’s begin, starting now, just one more time
until we catch the furthest stars

この瞳が宿す幻想に導かれ
きっと何度でも何度でも繰り返す
魅知の世界を見つけるまで

kono me ga yadosu yume ni michibikare
kitto nando demo nando demo kuri kaesu
michi no sekai o mitsukeru made

Guided by the fantasies and dreams housed in my eyes
I’m sure, time and time again, we’ll keep trying
until we find a mysterious, unknown world

星を探して　さぁ夜の街へ
今日も　運命の徒に身を委ね
私たちだけの夢を現に変える

hoshi o sagashite saa yoru no machi e
kyou mo unmei no itazura ni mi o yudane
watashitachi dake no yume o utsutsu ni kaeru

Searching for the stars, let’s go, into the night city
Today too, we’ll leave ourselves to the whims of destiny
and change our dreams alone into reality

深く暗い闇の其処から
あなたが呼ぶ声が
いまでも思い出せず胸を引き裂く
あなたはだれなの？

fukaku kurai yami no soko kara
anata ga yobu koe ga
ima demo omoi dasezu mune o hiki saku
anata wa dare nano?

From the depths of a deep darkness,
your calling voice,
unable to be recalled even now, rips out my heart
Just who are you?

心を渦巻く二つの色が
ワタシの最後の夢物語
今から始めよう　もう一度だけ
二人の想い出残す為

kokoro o uzu maku futatsu no iro ga
watashi no saigo no yume monogatari
ima kara hajimeyou mou ichido dake
futari no omoide nokosu tame

The two colours sweeping our hearts
make up the end of my dream story
Let’s begin, starting now, just one more time
for the sake of leaving memories of us together

この瞳を奪う現実に導かれ
きっと何でも何でも繰り返す
魅知の世界を見つけるまで

kono me o ubau yume ni michibikare
kitto nando demo nando demo kuri kaesu
michi no sekai o mitsukeru made

Guided by the reality and dreams stealing away my eyes
I’m sure, time and time again, we’ll keep trying
until we find a mysterious, unknown world

星の流れる　この夜の街に
今日も運命の徒が微笑んで
私たちだけの幻想が現実に変わる

hoshi no nagareru kono yoru no machi ni
kyou mo unmei no itazura ga hohoende
watashitachi dake no yume ga utsutsu ni kawaru

In the night city, with the stars shooting,
today too, with the whims of destiny smiling,
our dreams and fantasies alone are going to transform into reality

ふと耳を澄ませば
嗚呼、懐かしいあの声
世界の全てを暴く声
また出会えると信じて
溢れた涙

futo mimi o sumaseba
aa, natsukashii ano koe
sekai no subete o abaku koe
mata de aeru to shinjite
afureta namida

If you happen to clear your ears
ah, you’ll hear that nostalgic voice
The voice revealing everything about the world
Believing that we’ll be able to meet again
the tears flooded out

心に残る記憶に導かれ
きっと何でも何でも繰り返す
魅知の世界を見つけるまで

kokoro ni nokoru kioku ni michibikare
kitto nando demo nando demo kuri kaesu
michi no sekai o mitsukeru made

Guided by the memories remaining in my heart,
I’m sure, time and time again, we’ll keep trying
until we find a mysterious, unknown world

君を探して　また夜の街へ
今日は運命の徒を乗り越えて
私たちだけの明日を未来に変える

kimi o sagashite mata yoru no machi e
kyou wa unmei no itazura o nori koete
watashitachi dake no yume o utsutsu ni kaeru

Searching for you, to the night city again,
today we’ll overcome the whims of destiny
and turn our dreams of tomorrow alone into the reality of the future
