Point 2 is just AP and Range feat, you are making an assumption that there is an attack that traverse physically within that realm but definitely no, you need to concrete proof, otherwose shaking a realm isn't speed feat
My point was to show that the effects of the attack physically travel the entire realm, so an infinite distance. It's the reason the effects take time to reach the Seele's, it's not shaking the whole realm at once.
Point 3, wth is that? Is the "dream" or singularity infinite in size? I don't remember when playing this part
Black holes aren't infinite in size. Why would it matter? Escaping a black hole's Singularity is infinite speed, and the Spiritual Adam is compared rather strongly to functioning like a black hole.
If you have a problem with this and the FAQ, then the standards are what you have a problem with, and you'd need to get those changed.
Also, you misunderstand what a singularity is. A singularity is an infinitely dense point (in a rotating black hole it is a ring) with zero mass. Because of this spacetime breaks down, a regular "where" or "when" cannot be determined.
In Mathematical theoretical models, Singularities are points where the curvature of spacetime is infinite. That's it.
It's also worth noting that the actual science surrounding Singularities is only theoretical and there's multiple different interpretations. Infinite values like a Singularity's break the laws of physics because infinite values break the theory of relativity.
There's no real / complete or precise definition of a Singularity, so we should go off of wiki standards. Wiki standards say escaping a singularity is infinite speed. This IS escaping a singularity, so it is infinite speed.
1. Finality Kiana blast in Part 1.5 literally take time to reach to Griseo's planet and Sa, they are at the outer edge of the solar system
Extremely, extremely casual Kiana. If she missed Sa, the equivalent of aiming a centimeter off for her, it's stated that the planet would be destroyed. The attack also needed to be timed for Sa's escape anyway.
2. HoV Sirin take time to fly to the moon and get the gems and then fly back iirc in the manga
She doesn't scale to this. It wasn’t even Sirin flying too. It was Benares.
3. The bombing scene in Arc city literally have Kiana rush to the Bomb before it detonate and of course the bomb have a countdown. And later when she uses her HoV power it took time for her to fly to the space before it explode
She doesn't scale to this, not ARC City VD.
4. Time fracture and time stop ability narratively make no sense anymore if people having infinite speed
It is primarily introduced as a gameplay mechanic tbf. Even valks like Vita and Raven, who wouldn't have the Schicksal time fracture system, have time fracture.
