"I absolutely cannot forgive you, Rengoku-san." You seethed under your breath and clenched your fist. "No matter what."

The blonde man pursed his lips. His usual fiery tact reduced to mere flames. A solemn shadow cast over his face as he muttered, "If it has to end like this, then I will have no choice. It has been nice knowing you, (L/n)."

Senjurou and Chieko, your little sister, stood obediently silent and bit their lips while clinching onto their shirts. They held onto their bated breaths. Sweat rolled down their foreheads as their eyes would not tear away from the two adults like there was a spotlight over the two of them.

They had their eyes locked in a death stare, unrelenting. You gulped as Kyoujurou's hand twitched. Whatever that he planned to do could end badly either way yet you didn't have a plan. You took a deep breath and looked at your hand.

Kyoujurou gazed at you kindly one more time—like a final goodbye— and set his hand to the middle of the table. Your eyes widen.

*A week prior*

"A rival?" You exclaimed and jumped on the pillow you were hugging. "A rival in your school?"

Chieko stuck her lower lip out and huffed, "What are you acting surprised for?"

"The genius of the household, (L/n) Chieko, has a rival!" You broke out laughing and rolled to your back.

"I didn't invite you to talk crap about me in my room!" She groaned and crawled over to her pink study desk. She slapped her hand on a piece of paper and dragged it back to you. "I have no hope for the interclass quiz... why must it be part of the competition anyway?"

"It's the annual competition tomorrow?" You smiled in nostalgic awe. "Man, I totally trashed that."

Chieko glared at you and swatted the paper in your face. "You flunked the competition on purpose! I know you did!"

"How'd you find out?"

"You're the one who taught me all the things the teacher left out," Chieko jabbed a finger at you, "and you hate competitions!"

"I just don't like teachers, Chieko." You took the paper from her hands and spoke aloud, "That history teacher of mine was an asshat, so I said: 'The sun is a deadly laser and hence ninjas are on the rise'."

"You could've won the creative writing competition with that." She grinned cheekily, rolled and knocked into you.

"Then you should study demons back in the Taisho era. Maybe it will come out for the test."

"Demons? There are not much government records on them, except for famous excerpts written by Tomioka Giyuu and Kamado Nezuko." She punched you in the shoulder. "There's no way it will come out."
