Mitsuki stood with her parents, Ai Kirisawa and Prince Asante, within her family's Training Grounds in XCalibur AOP 2.
"From here on out, I want you to imagine the Universe as a balloon filled with Water and Solid Objects floating within the Water" Prince said.
"Okay" Mitsuki nodded.
"I'll let your Mom take over from here. She has something to teach you" Prince said.
Mitsuki nodded.
"Every object with mass occupies a fixed region within space. The region occupied by the object in turn displaces some amount of space. This is balanced out by the inward pressure exerted on the body by the Universe in its attempts to maintain the integrity of its form. To get a clear picture, try imagining the solid objects within the balloon displacing some water as they are added to the balloon and this strengthening the overall elasticity of the balloon as it nears its elastic limit" Ai explained.
"I see what you're getting at" Mitsuki realized.
"The larger the body, the more of space it displaces" Ai said.
"How come?" Mitsuki asked.
"The body is filled with potential energy by virtue of its mass. The larger the body, the greater the potential energy but as you know, Planets aren't stationary but orbit Stars so all this potential energy is converted into kinetic energy. The potential energy in stars in turn is transformed into Heat and Light Energy. The greater the energy involved in maintaining the body's mass the more of the fabric of Space it displaces. This is basically how Gravity works" Ai explained.
"I see, in other words, every object with mass possesses the capacity to generate a Gravitational Wave by virtue of the Potential Energy within the body?" Mitsuki wondered.
"Exactly, and this Potential Energy can be converted into other forms of Energy. It is also possible for the potential energy within a body to grow as external forces act on the body hence a bullet doesn't carry as much force on its own until it is fired from a gun. Usually, the Potential Energy within a body grows as its mass grows thus it could be said that by focusing enough energy to a single point, one could construct or move objects whose mass is proportional or equivalent to the energy being focused" Ai explained.
"I see" Mitsuki said.
"You've been in tune with the Moon's Gravitational Force since your infancy. I want you to learn to harness Gravity from other objects as well" Ai said as the Training Ground transformed revealing a lake with a ball floating at the centre of it.
"Call that ball to you with Gravity. Try bending the fabric of space surrounding the ball" Ai instructed.
Mitsuki walked to the edge of the Lake. She watched the Waves Of Water carefully.
"I should probably try bending the space behind the ball" she thought to herself and stretched her arms forward.
"I'm guessing I can't utilize Lunar Gravity" Mitsuki asked.
"No, you can't" Ai said.
Mitsuki sighed.
"This is going to be harder than I thought" she sighed in exasperation.
"There's a reason for this. Your Lunar Gravitational Abilities grow stronger as the seasons approach a Full Moon. However, it weakens proportionally as the seasons inch towards a New Moon. If you don't learn to harness Gravity from other bodies, you'll be vulnerable if you are attacked by adversaries during a New Moon" Ai said seriously.
Mitsuki gulped.
"I've just got to do this" she said with determination and shut her eyes.
She could clearly sense the Moon's Gravitational Field around her body but this time she didn't sync to these Waves. She could feel other Waves stronger than the Moon's Gravitational Waves. There were three dominant Waves. The weakest was the Moon's Gravitational Wave. The second weakest was the Earth's Gravitational Waves. She could clearly see the Earth's Waves displacing the fabric of space all around her as well as the inward pressure exerted by the universe as it attempted to balance this out. The strongest Gravitational Waves came from the Sun keeping all the Planets within the Solar System on their respective orbits. The Waves of the distant Planets were so eclipsed by these three Waves that they just seemed like background noise. Mitsuki synced to the Sun's Waves. She opened her eyes.
"TORRENTIAL PUSH OF THE SUN'S GRAVITATIONAL FORCE!" she called as a sudden downward force from above pushed on the Lake generating powerful Waves that pushed the ball towards the Land.
Mitsuki reached into the Lake and removed the ball.
"Congratulations Mitsuki. You've finally learnt to sync to the Sun's Gravitational Waves" Ai said happily.
