This is the song sung by “Kiria” in the Shin Megami Tensei x Fire Emblem (幻影異聞録シャープエフイー) trailer that came out April 1st on the Nintendo Direct. (Video/song below for reference)
I found a transcript of the lyrics on 2ch written by Japanese users, so here they are in Romaji and translated!
The format:

壊したい、大事そうに抱えた、私を全部
kowashitai daijisou ni kakaeta watashi o zenbu
I want to destroy all of the important things I’ve held onto
君がこの孤独を、痛みを、癒やすの
kimi ga kono kodoku o itami o iyasu no
You can heal me of this painful loneliness
(コーラス)Reincarnation , Realization
(Chorus) Reincarnation, Realization
――消えてしまいたい
...kiete shimaitai
…I want to disappear
眠らない街のざわめき
Nemuranai machi no zawameki
The noise of the endless city streets
愛想笑いの憂鬱
aisowarai no yuutsu
The melancholy of false smiles
本音なんて、いつかどこか見えないふり
honne nante itsuka doko ka mienai furi
The real face behind them, in a way that has never been seen
誰だって不安なんて
dare datte fuan nante
Whenever someone is anxious
そんな言われなくても、分かってる
sonna iwarenakutemo wakatteru
Even if they don’t say it, we know it
壊したい、大事そうに抱えた、強がりなんて
kowashitai daijisou ni kakaeta tsuyogari o nante
I want to destroy all of the important things I’ve held onto, give me the courage
でも、素直になれない
demo, sunaoninarenai
But, I won’t be up front about it
迷っても、悩んでも、君が求めるなら
mayotemo nayandemo kimi ga motomerunara
Even when I’m lost, even when I’m troubled, I still want you
せめて、この孤独を痛みを壊して
semete, kono kodoku o itami o kowashite
At least, I will destroy this painful loneliness
(コーラス)Reincarnation , Realization
(Chorus) Reincarnation, Realization
――生まれ変わりたい
…umare kawareritai
I want to be reborn
（台詞）絶対に逃がさない
(Speech): I will never escape.
