Dude all of this
だれ
すべて 誰かとの「つながり」が
そんざい
あればこそ存在するものなのだ。
Everything exists precisely because of one's 'connections' with someone
そして…
いまキズナは世界をもこえて…
And…
Now, Bonds transcend even the world…
すべては
キズナから生まれるエネルギー…
For all things
are born from the energy of Bonds…
Put together just straight up means we've been lowballing Brothership this whole time I shit you not
Bonds create EVERYTHING, and spread
beyond each universe, creating an infinite cycle of creation, lining up with Dr Vulko calling it "infinite energy".
And acting as a direct inverse to Glohm, which causes an endless cycle of destruction.
It creates everything and spreads by ascending beyond every universe it's present in, it's definitive evidence AND MORE.
Not to mention that the Uni-Tree is partially based off of Yggdrasil, with Reclusa being partially inspired by Nidhogg, a snake trying to destroy the world tree, the source of all life.
As such, the intent is clearly there for Bonds being a UES that binds and CREATES the 2-A multiverse.
