Shigure
The falling tears wet your cheeks on that morning of departure But look forward quietly Lift your head, I remember your awkward smile Yes, it feels like I've been asleep for a long time I am going now, embracing the memories of time Thank you, thank you, I'll say it again and again I, we, will never forget Echoing the sound of time, beyond the rainy sky Someday again in that sea I'm sure we'll meet again The fading pain wets your eyes in that winter of sorrow But surely look forward Raise the anchor, protect your friends, and walk the path of no return Yes, it feels like I've been fighting for a long time Falling to the far side of time, to the end of the waters Thank you, thank you, I will surely say it I will never forget you Leading the sound of time, beyond the rain clouds Someday again in that sea We can meet with a smile, can't we? On that day, living together I was surely dreaming a dream I wouldn't wake from Five colors of sunlight piercing through the clouds Thank you, thank you, I'll say it without hesitation I will never forget everything The sound of time shines, the rain clouds vanish Someday again Surely— Thank you, thank you, I'll say it at the very end I will never forget you Echoing the sound of time, beyond the rainy sky Someday again in that sea Someday again in that sea
Shigure of Sasebo
My feelings drawn upon the sea I want to deliver them now, beyond this rain My yesterday, which wasn't honest Must look so selfish to you Even on rainy days, if I could be with you I thought it wouldn't be so bad But I won't forget that autumn night A lonely rain, and then, the ending winter Time quietly closed, now run! The promise of that day drawn upon the sea Sadness, time, dreams, I embrace them all even now Toward my continuation drawn upon the sky The rain stops now, with you, Shigure of Sasebo Even if there are things I want to tell you Why can't I say them well? Even on winter days, if I spend them with you I thought it wouldn't be cold I won't forget the heartache of the dream I held The kindness, and the pain Time that quietly closed, now race! The tears you shed that the rain washed away Are beautiful like the morning dew, I embrace them all in my heart In the smile of tomorrow drawn by the rainbow The village rain clears, you are the Shigure of Sasebo Hey, do you remember? The promise of that day Sadness, time, dreams, I embrace them all in my heart Passing through the evening shower that drew a rainbow The future we two run toward, let's go together The promise of that day I wished upon the sea Sadness, time, dreams, I embrace the heart of now Beyond the prayer I wished upon the sky The rain stops now, for you, Shigure of Sasebo
Future (Now)
The rain is stopping Even now my heart leaps The morning for you and me awakens Aiming for the shining harbor I won't forget your eyes as you run The wind, the moon, and the snow Melting into the spring sun Memories and the sky, the waves burning The rain and the tide are like a heat haze I'll embrace them until they reach the clouds Now, reach out your hand I'll run, I'll run, through autumn and past winter I'll run toward tomorrow, the end of the pine grove comes into view Sparkling sounds of waves, spray rising and dancing in the sky Dreams we haven't talked enough about, the sea that connects us I'll deliver it to you, the future (Mirai) Even now it remains in my heart Embracing the night of you and me Listening to the sound of the waves I won't forget the time you spend sleeping The white time, the village, the town I'll leap over them Memories and the sky, the sunset burning Crossing spring and May, the sea and the mountains Reaching from the river A refreshing feeling, I feel it now I'll run, I'll run, I am living today right now I'll run, a summer day, beyond that hill comes into view Smooth sandy beach, throwing off my shirt and dancing in the sea Dreams I can't fully convey, the sea I look up at I will deliver it, the future (Mirai) The destination, the path illuminated Even if the sun sets and darkness comes Someday, the morning will return And we will stand up We don't want to lose right now I'll run, I'll run, through autumn and past winter I'll run toward tomorrow, the end of the pine grove comes into view Sparkling sounds of waves, spray rising and dancing in the sky Dreams we haven't talked enough about, the sea that connects us I will live with you, in the future (Now) Run through!
