Mushoku from Detective Conan by Azumi Uehara

Ikura naitemo namida tte mono wa
Kesshite kareyuku koto nado nai to shirima shita
I learned that no matter how much you cry
Your tears will never dry up
Kono hoshizora ga konna kagayaku no wa
Kono doreka ni kimi ga iru kara nano deshou
The reason this starry sky shines so brightly
Must be because you're one of them

Kimi ga inaku natteta nee hitori ni shinaide
Me ni utsuru mono ga subete yugami hajimeteta
You're gone now, don't leave me alone
Everything I see has begun to warp

Kao wo agereba sora wa hirogari
Hoshitachi wa kagayaku keredo
Hoshi ni te ga todoku hazu nai
Doushite konna sora wa tooi
Kimi ni aitai
If I look up, the sky spreads out above me
The stars are shining, but
There's no way I can reach them
Why is the sky this far away?
I miss you

Kono hoshizora ga konna setsunai no wa
Kono doreka ni kimi ga iru kara nano deshou
The reason this starry sky is so bittersweet
Must be because you're one of them

Kimi ga inaku natta nani mo kamo naku natta
Me ni utsuru mono ga
Subete iro wo ushinatta
You're gone, everything is gone
Everything I see has lost its color

Kao wo agereba sora wa hirogari
Hoshitachi wa kagayaku itsumo
Ichiban taisetsu na hito to wa
Doushite issho ni irarenai
Kimi ni aitai
If I look up, the sky spreads out above me
The stars are always shining
Why can't I be with
The one I love most?
I miss you
 
Soro soro hi ga noboru machi ga zawameki dasu
Soshite hirogatteku mushoku no sekai ga
The sun will soon rise, the town is stirring
And the colorless world that spreads out before me is...

Kimi to awa nakereba yokatta to
Koukai suru hi sae atta
Soshite ima kono sekai kara
Hoshizora ni mukatte tobitatsu
Yatto aeru ne
There've been days I was full of regret
And wished I never met you
And now I'm going to leave this world
And fly up to the starry sky
To finally see you
