Mokou, Kaguya, and Sakuya will use their powers to create a ship that can surpass the speed of light, enter the Big Crunch's singularity, and create the universe (Big Bang).

When the creation of the universe (Big Bang) happens, Eirin will manage the universe's beginning, and prepare everything so that the Solar System, the Earth, and Gensoukyou can be born.

※To cause the Big Bang, an infinite amount of energy must be granted to the singularity. Below is the method to acquire infinite energy.

Mokou will use a spell, aiming towards the back of the ship.

Kaguya's "power of eternity" will fix Mokou's spell and the environment inside the ship in place.

Sakuya will compress the space-time in front of the ship.

Thus, the ship will surpass the speed of light, and can acquire infinite mass.

The Big Crunch's singularity's appearance will be 300 billion years from now, but when the ship reaches the speed of light, due to the Theory of Relativity, time dilation effect (the "Rip Van Winkle" effect) will happen, and the time inside the ship will stop. In the experience of everyone on the ship, they can arrive at the singularity 300 billion years later in just a moment. "Urashima effect" in Japanese.

Furthermore, 1,000 years before the Big Crunch happens, the universe's stars and dust will compress, and there will be almost no space left inside the universe, but as the ship has acquired infinite energy, it can destroy every obstacle in its path and reach inside the singularity.
