Illuminate-imp. tomorrow (obj), now, heart conveyed-along message

照らせ is the imperative form of 照らす ('illuminate'). 伝う ('be conveyed along' — for things that travel along a path) makes the message a current running through the heart, like tears down a cheek.

Me-with very-resembling pain (obj) open-up did-for-me person

打ち明ける ('hit-open' = open up about, confess a secret) is the verb for revealing what you've been carrying privately. 打つ ('strike') + 明ける ('open / reveal') — together: forcibly cracking something closed. 〜てくれた ('did it for me') gives the gift-direction: the other person gave the speaker the gift of their confession.

Suddenly, alone-isn't-it-is (quoted-thought) could-think

思える is the POTENTIAL of 思う — 'be able to think / be able to feel.' Distinct from 思った ('I thought'): 思えた means the speaker became capable of thinking it (which had been impossible before). The line tracks the moment of inner unblocking.

But flowed tears, clenched warmth (obj)

噛みしめる ('bite-tighten') is the verb for biting down on something to savor or endure it — used for clenching teeth in pain, but also for tasting deeply. 噛みしめた温もり ('warmth I clenched') captures both the savoring and the suppression.

Forever, I as-for, can-keep-embracing-I-wonder

抱きしめていられる layers 抱きしめる ('embrace tightly') + 〜ている (be embracing) + potential られる (can / be able to). The compound potential expresses 'be able to remain in the embracing state.' 〜かな softens it into private wonder.

Get-hurt-and get-hurt-and, cry-and cry-and, become-strong-imp., all

傷ついて + 傷ついて doubles for emphasis: not just 'get hurt' but 'get hurt and hurt and hurt.' The repeated te-form has the cumulative-action force seen in shounen anime: piling up damage. 強くなれ is the imperative of 強くなる ('become strong').

Eye-in is-reflected that scenery as-for, eternity-ly, eternal heart-toward straight goes-on-connecting

永遠 ('eternity') used twice in different forms: 永遠に (adverbial 'eternally') + 永遠な心 (adjectival 'eternal heart'). The repeated kanji-pair gives the verse hymn-like resonance.

Encounter, unforgettable farewell, accumulating-when, same become

積み重なっては uses 〜ては (covered earlier) for the recurring/cumulative 'each time they pile up.' 積み重なる ('to be piled up / accumulated') is intransitive — the things stack themselves. The line: across enough events, opposites become indistinguishable.

Limit-no dream seek, how-many-of nights (obj) cross

限りない is the negative of 限り ('limit / boundary') used adjectivally — 'without limit / boundless.' Common with 限りない愛 ('limitless love'), 限りない可能性 ('limitless possibility'). いくつもの ('many a / countless') uses も on the question word いくつ ('how many?') for indefinite plural.

Now this-way I as-for here-at am-standing-yo

こうして ('like this / in this way') is the manner adverb that points to the speaker's current state. Compare そうして ('and so' / 'in that way' — referencing prior context) and ああして ('like that — over there'). こうして emphasizes the immediate-here stance.

Already 100-ten-thousand-times pass-even-if, end-up-astonished extent, believe-through-imp.

100万回 ('one million times') uses 万 (10,000), the higher counter base in Japanese. 信じ抜け is the imperative of 信じ抜く — 信じる + 抜く ('see through to the end'). The 〜抜く suffix appears in 守り抜く (Yuusha) and 戦い抜く (Phoenix), all meaning 'V to absolute completion.'

Eventually sun-of-light as-for, pierces surely, release-imp. rainbow-of-light

やがて ('before long / soon') is the literary 'eventually' — more atmospheric than the everyday もうすぐ. 放て is the imperative of 放つ ('release'). 虹の光 ('rainbow's light') closes the chorus with the title image.

Eyelid-of-back smiles you (subj) softly, any-time-even hesitate-without advance strength had-become right?

瞼の裏 ('back of the eyelid' = behind closed eyes) is the standard idiom for 'in my mind's eye / when I close my eyes I see ~.' になってた is casual contraction of になっていた ('had become') — past perfect of state-change. The line is a retrospective realization: 'all this time, you'd been my strength.'

Rainbow-of-sky, feelings if-it's, here-at exists

想いならここにある ('if it's feelings, they're right here') is a topic-conditional with 〜なら: 'as for feelings — they exist here.' The structure offers feelings as an immediately-available answer.
