Fundamentals of Resonance

Reagan dragged Nova to his dorm room.

Nova stared at the familiar door blankly.

『...What are we doing her-?』[Nova]

Before he could finish his sentence, Reagan kicked the door down.

『I-I-I COULD HAVE JUST OPENED THE DOOR!』[Nova]

『...It was to wake up the person inside.』[Reagan]

He walked forward, staring directly at a terrified Freyana, once he was inside.

『...What's going on..?』[Freyana]

He casually tossed Nova onto the bed, prompting Freyana to catch him with her mana.

『Nova?!』[Freyana]

She flinched a little, as if some noise or flash of light surprised her.

『...I knew it.』[Reagan]

Reagan sighed and raised his eyebrows.

『You two are practicing "Resonance", right?』[Reagan]

『...Huh? How did you know?』[Nova]

『Each of your manas has already become slightly tinted by each other.』[Reagan]

He covered his eyes with his hand, causing them to change in color ever so slightly.

『...This is in anticipation for the opening match to the tournament, right?』[Reagan]

Nova paused for a moment before reluctantly nodding.

『...Great.』[Reagan]

A sinister smile appeared on his face, sending shivers down both Nova and Freyana's spines.

『So happens that the teacher of that class is someone that I have a grudge against… I think I'll use this chance to gain some class points and wipe the floor with him…』[Reagan]

He put on a phone that was similar to Nova's before he started

His volume suddenly dropped, mumbling just enough for them to understand some words.

『...Honey… let's meet… need some help… okay…. love you, bye.』[Reagan]

Freyana giggled quietly while getting closer to Nova.

『...Aren't they so cute?』[Freyana]

Nova had to try his best to suppress his laughter.

『...Pfft-..Mhm.』[Nova]

Reagan hung up and turned back to them.

『...Still, kids are dating so young nowadays.』[Reagan]

Freyana's face filled with pink.

『Huh?!』[Freyana]

『...Anyways, Nova. Open up an Area to the practice area. Raina will be there soon.』[Reagan]

『...Got it. Area.』[Nova]

...

After a bit, Raina's car appeared.

『Hey-hello! What's going on?!』[Raina]

She exited the car before dematerializing it.

『They're practicing Resonance, so I wanted your help trying to… explain it.』[Reagan]

『Hi, Mrs. Raina!』[Freyana]

They both waved at each other energetically whilst Nova and Reagan stared at each other.

『Oh! I did a study on Resonance after we graduated from Genesis, so that's kind of my expertise!』[Raina]

She looked at Reagan and smiled.

『Honey, can you pass me one of thos-』[Raina]

He tossed a small disc to her before she could even finish asking.

『Thanks, love you!』[Raina]

She put the disc on the floor and pressed on it, causing it to start making a loud whirring noise.

『The disc is a small mana field that holds mana in place and enables hyper-realistic images to be created.』[Reagan]

『...That's so cool!』[Nova]

『Isn't it? But, it's only within a small range, as will be shown by the net.』[Reagan]

A giant net spread out in all directions and surrounded the four of them.

『Right! Resonance is a special, beautiful thing! It's when the intention of two individuals line up, and the differences in both of them amplify the strength of the action.』[Raina]

She made four balls of color- Blue, green, purple, and orange.

『I'm sure you kids can tell what these colors mean, right?』[Raina]

『Blue is me, green is Freyana, and the other two are…』[Nova]

『You and Reagan, right?!』[Freyana]

Raina grabbed onto Reagan's arm, causing his face to go beet red.

「...They kind of remind me of…」[Nova]

Freyana grabbed Nova's arm in the same way, causing Nova to go red too.

「...Oh.」[Nova]

『Right! That's why he called me here for the both of you! You can't resonate without someone else!』[Raina]

Nova concentrated on the "someone else" part.

「Not specifically one person..?」[Nova]

Reagan stared at Nova preemptively, as if expecting something.

『...So you could do it with other people besides your partner?』[Nova]

Reagan nodded his head.

『Resonance can be done by people with close bonds. Not specifically romantic bonds. There are a couple of people that Raina and I can resonate with, but our Resonance is the strongest with each other.』[Reagan]

『Yeah, look at this!』[Raina]

She created a floating phantom of her and Reagan holding each other's hands.

『This image looks so realistic..!』[Nova]

『Oh? Watch this then, Nova!』[Raina]

She waved her hand around, changing the setting to that of a desert, with hundreds of beasts around them.

『So… many…!』[Nova]

Mana began to burst from the phantom of Reagan and Raina, in orange and purple.

『The differences in each person are what makes Resonance strong, whereas the similarities are what makes Resonance able to be used.』[Reagan]

『That's why the chant you're about to hear is about the other person you're casting with. Though, Resonance's strengths extend far past just what you're about to see.』[Raina]

The two phantoms began to chant, increasing the mana pouring out of them.

『Violet grace and regal purple, setting all in your domain right, punishing all that may bleed corruption into this world…』[Raina]

Purple began to exit Reagan and surround them like a fine mist.

『Scarlet flame and vermillion providence, turning to ash all that may dirty you, let your warmth spread…』[Reagan]

This time, orange began to exit Raina before surrounding them as the purple did.

In unison, the two floating people thrust their hands out.

『EMPYREAN FLAME DYNASTY!』[Reagan & Raina]

Hundreds of giant purple spears manifested in the sky before impaling the hundreds of beasts and sending waves of flame each time one made contact.

『...Amazing..!』[Freyana]

Nova stared at the giant view with his jaw open.

After a couple of minutes of explosions, the spears exploded into a giant wave of flame that enveloped the creatures.

『So… strong!』[Nova]
