Yume Sekai (ユメセカイ)

Since-when (uncertain), this chest in, is-wavering light

いつからか ('since who-knows-when') is a stock J-pop opener for the inner glow that's always been there. The か turns 'when' into 'somewhere' — emphasizing the speaker's lack of awareness of the start.

Want-to-let-go (emphatic) not

手放す ('to let go of / give up') = 手 (hand) + 放す (release). Used both literally (放す: drop the keys) and metaphorically (give up a dream). 〜たくはない uses emphatic は to single out 'letting go' as the explicitly unwanted action.

Detour even-do, stumble-even, here at all-along all-along is-shining

遠回り literally 'far-going-around' — taking a longer path. Often used metaphorically for slow growth or indirect lessons. Repeated ずっと doubles the duration — 'forever and ever'.

Bell's sound (subject) a-little lonely-and

鐘 ('bell, large') vs ベル ('small bell') vs 鈴 (すず, 'tinkling bell'). Each has distinct cultural associations — 鐘 evokes temple bells, school bells, the long, resonant kind.

Once-more strongly, this-time (topic) highly raced-through

Still repeat reality also, star's number's wishes also

星の数 ('the number of stars') is a Japanese idiom for 'countless' — the same way 'as many as the stars in the sky' works in English. 願い事 ('wishes') traditionally are ones you write on tanabata strips or whisper at shrines.

Aim-for should tomorrow (object) want-to-find

Verb-dictionary + べき expresses 'should / ought to': 行くべき ('should go'), 守るべき ('should protect'). Slightly formal/literary; often used for principles or duties. Negative: 〜べきではない.

Continue-wavering even, chest's depths in strongly all-along all-along

Shone city in, ideal's days (object) was-spending

日々を送る ('to spend days', literally 'to send days off') is the standard phrase for 'living one's days / leading a life'. Same として: 平和な日々を送る ('lead a peaceful life').

Won't-get-hurt place aiming-for, wings only sought but

傷つかない場所 ('a place where one can't be hurt') is the song's central illusion — the dream world of SAO promises this, the song confesses chasing it was wrong. Refusing to live anywhere you can be hurt is refusing to live.

This back on, just one

World (object) felt as-is good

〜たままでいい ('it's fine to leave it as it was X-ed') is a common reassurance phrase. 寝たままでいい ('you can stay sleeping'), 立ったままでいい ('staying standing is fine').

Smile's color also, fated-encounter's color also, more more keep-changing

巡り合い (literally 'going around and meeting') = 'fated encounter / chance meeting'. Heavier and more romantic than 出会い ('a meeting'). The kind reserved for love, mentors, lifelong friends.

Answer (subject) exist-and, let's-aim trying

Volitional + として ('try to do X') signals an attempt rather than achievement: 行こうとして ('tried to go'), 食べようとして ('tried to eat'). Useful for 'tried but didn't quite succeed' framings.

I also surely this world with resemble

似ている ('resemble') always uses the 〜ている form — never plain 似る. The progressive ending here doesn't mean 'in progress'; it's just how this verb is conjugated for the 'be similar' meaning.

Keep-believing, new tears with, started-becoming-visible future

Verb-て + くる (= 〜てくる) marks a change becoming visible from the speaker's perspective: 見えてくる ('coming into view'), わかってくる ('coming to understand'). Distinct from 〜ていく which marks moving away.

Not-be-scared good, heart's pain even

怖がる ('to be scared') is what someone else does — different from the い-adjective 怖い ('I find it scary'). 〜なくていい is the standard 'don't have to' / 'no need to'.

Was-looking-at scenery (topic) surely surely overlap

Limitlessly, eye's-front in opened, endless world

果てない ('endless / without limit') uses 果てる ('to reach an end'). 果て itself = 'the very end'. SAO's Aincrad = 'a world without limits' is exactly the song's theme.

Even-if dream even good

たとえ〜でも is the emphatic 'even if' construction — a fixed pair. たとえ (set up) + でも (confirms). Common: たとえ雨でも (even if it rains), たとえ嘘でも (even if it's a lie).

Continuously continuously echo-go, softly softly is-shining

Reduplicated mimetic adverbs (ずっとずっと, そっとそっと) doubled for emotional weight — same J-pop trick used in many lyrics. Doesn't change the literal meaning, but adds rhythm and intensity.
