Saeko Busujima: "Cough, cough, perhaps I can explain what a vector is."

Saeko Busujima: "Simply put, a vector is a quantity that has both magnitude and direction."

Saeko Busujima: "As for Vector Manipulation…"

She didn't continue, only feeling that her guess was too far-fetched.

Ren: "You guessed correctly. Vector Manipulation means you can arbitrarily manipulate the direction of vectors, thereby manipulating these forces."

Ren: "However, the vectors in this ability have a relatively broad extension in the physical sense."

Ren: "Besides vectors in physics such as momentum and electromagnetism, it also includes physical phenomena with defined directions, such as light, radiation, infrasound, and the oxygen environment."

Ren: "These are all within the controllable range of Vector Manipulation."

Ren could only say that this was Hippo physics; never define it using ordinary physics!

March 7th: "Wow… my head is spinning. These are all words I recognize, but why do I not understand a single thing when they're put together?"

Aqua: "This goddess doesn't need to understand; having divine power is enough!"

Exusiai: "I understand. It's amazing. It feels much stronger than Originium Arts."

Saeko Busujima: "The ability to arbitrarily manipulate vectors… truly incredible."

Ren: "Haha, no matter how strong an ability is, it needs to be upgraded."

Ren: "Enough talk, I'm in a good mood, I'll send a red packet."

[Ren sent a doomsday points red packet!]

[Exusiai has claimed it!]

[March 7th has claimed it!]

[Aqua has claimed it!]

[Saeko Busujima has claimed it!]

March 7th: "Wow! I got 100 points! I'm the luckiest! Thank you, boss! Love you!"

Exusiai: "Claimed 80 points, thank you, boss!"

Aqua: "Why am I the lowest again, only 50 points? Has the goddess's luck abandoned me?"

Saeko Busujima: "70 points, thank you, Ren-kun."

Ren didn't care. Only 300 points; it was nothing compared to the ability he drew. And he also tested all the group functions at once, so it was worth it.

"Ren, can you hear me?"

A clear, anxious call came. Ren's gaze returned to reality, only to see complete darkness. He instinctively reached out.

"Ugh!"

A gasp of surprise.

"..."

Ren was silent. He seemed to have touched something he shouldn't have. He quickly retracted his hand. He awkwardly coughed twice.

"Ahem, so, what happened?"

"..."

After a brief silence, her voice trembled slightly in the darkness. "The zombies outside the window seemed to be making strange noises, so I turned off the light."

Ren groped his way to the window. This time, having confirmed Yukino's position, he didn't grope around anymore. He lifted the blanket a little. He gently opened the window. He heard a cacophony of roars.

"Roar!" "Gah-roar!" "Hiss-roar!"

Endless groups of zombies roared and shrieked as if they were on drugs. He quietly closed the window and pulled down the blanket. Ren stated his guess.

"I think it's because of the night; the zombies have become more active."

"Try not to turn on the lights at night, so we don't get disturbed. I still want to get a good night's sleep."

"Alright." Yukino replied.

The two fell into a silent stillness.

Finally, it was Ren who broke the awkwardness.

"Well, how about I go to sleep first?"

"Alright."

Hearing the sound of Yukino standing up from the bed, Ren lay down on the bed. Yukino slept on the bed opposite him.

In the darkness, Yukino's small hand gently pressed down on her skirt hem. She pursed her lips. There seemed to be a warm sensation there still. Coupled with it being the first time sleeping in the same room with a boy, the tension, shyness, and restlessness made her unable to fall asleep peacefully.

Ren, on the other hand, had been busy all day and was quite tired. He quickly fell asleep, his breathing even.

Hearing that Ren had fallen asleep, Yukino also tried to relax. She regulated her breathing and closed her eyes.

*****

Rustle, rustle.

Hearing the movement, Yukino opened her eyes. She saw Ren already up, doing stretching exercises with his upper body bare. He sat up.

Ren heard the movement. He wiped off the sweat and turned to say, "Did I wake you?"

"No, I just woke up."

As he spoke, Ren sat opposite her. He was wiping sweat with what appeared to be a clean towel. Yukino's gaze fell upon his smooth skin and well-defined muscles, coupled with Ren's healthy and handsome face. She couldn't quite tear her eyes away. She somewhat understood why some girls liked handsome boys with good figures.

"Hmm?"

Ren noticed her gaze. Yukino quickly averted her eyes, stiffly changing the subject.

"Do you have any plans for today?"

"I'm planning to clear out the zombies, but I'm worried about you here."

Feeling his concern, a warmth spread through Yukino's heart. "Thank you for all your help. I'm only alive because of you. Don't let me be a burden to you. If I can repay you, I don't care if I die."
