Izuku and Shiki opened the door t discover that there was nobody in the classroom. "Huh? Shouldn't there be someone already here?" Izuku asked to himself. Shiki looked around and saw the clock. "It  appears we arrived half an hour early. It is good to arrive early in your schedule but this is too far."

          Izuku bowed and repeatedly spouted apologies. "It's fine. Being early is always good." Shiki said as she took a seat in an extra chair in the back. Izuku headed to his own chair and fidgeted around in it. Izuku waiter for about ten minutes, which felt like years.

          Then he heard the door open. "Ah, Midoriya. You're here early." Iida said and closed the door. He didn't notice Shiki in the back, watching him carefully. "Good Morning Mr. Iida." She greeted. Iida jumped back in surprise, but said. "Good Morning Madam!"

         Iida bowed and bowed and kept making his hand gestures. "Calm down. You're being too energetic. You might break your arms or back." Shiki scolded lightly. She smiled at him. Iida nodded and headed to his seat fidgeting as well.

Soon, everyone filed in they didn't notice the unexpected guest. "Good Morning Class 1A." Shiki said. Everyone turned to her. They were confused as to who she is. Their gazes switched between Izuku and Shiki. And they all said one thing at the same time. "Is that your mom, Midoriya?"

Izuku's face paled while Shiki chuckled light-heartedly. "I'm not. I'm Shiki Eiki. You may know me more as the Yamaxanadu." Everyone suddenly became dead quiet. "Who the fuck is that?" Everyone except Bakugou.

Shiki's expression became sharp and stoic. "Watch your language, young man." She scolded. Everyone was shocked. No one except the teachers had the guts to talk back to Bakugou. "You don't get to tell me what to do!"

That was his mistake. Shiki threw her rod. The inscriptions on it glowed gold. As soon as the Rod hit Bakugou, he was suddenly sent flying into the blackboard. "Yes I can. My quirk is called Judgement. It allows me to be simultaneously the weakest and strongest person there is."

Everyone was confused. She was very cryptic. "If the person I'm facing is a good person then I can't defeat them. If a person I'm facing is very sinful, they are nothing but insects to me." She explained. Everyone nodded in understanding. "That's so manly!" Kirishima yelled.

Shiki looked at him oddly. "Kirishima Eijirou. Do not expect everyone to follow your standards. Understand that everyone is very different." She said. Kirishima nodded. Soon the door opened again and revealed Aizawa.

Aizawa immediately noticed Shiki.

...

Aizawa closed the door. They heard footsteps outside that were slowly fading. "Oh no you don't." Shiki said. She began walking towards the door and opened it. Aizawa then began running. Shiki was very quick and was running after him.

She produced another rod from her belt and threw it at him. It hit Aizawa behind the head and knocked him out. The papers that Aizawa was holding were scattered everywhere.

Shiki gathered the papers and fixed them neatly. She brushed off the dust that coated some of them. She then grabbed Aizawa by the legs and dragged him. She pulled him with no difficulty and opened the door to Class 1A.

Everyone was shocked to see their teacher knocked out. "So strong..." They all muttered. She easily defeated their Teacher who could easily defeat all of them. "Like I said. I'm simultaneously the weakest and strongest person." Shiki said.

She picked Aizawa up and slapped him hard. He immediately woke up and wrapped her in his capture gear. Shiki remained calm and just removed the capture gear off of herself.

"You're late. You should be more time conscious since you're a teacher. I don't care if you're very sleepy. Sleep early." She scolded. Aizawa was visibly afraid of her. "Now go and teach your students. I'm surprised that you have all 20 of them."

"Um, ma'am. He expelled one and Midoriya filled her slot." Sato informed her. A vein bulged in her forehead. "Eraserhead. You shouldn't expel students easily. Each student has their own set of obstacles to face, and it's a teacher's job to identify and help them through it."

She paced around in front of him. "And don't judge children very easily. Judging them is like judging unfinished art. You have to wait until they get finished before you judge them."

          Aizawa bowed his head until it was touching the floor. "I apologize Ma'am." Aizawa said as sincerely as he could. 'Lying~!' Izuku thought. "Midoriya, can you tell me the authenticity of his words." Shiki requested.

Aizawa grunted. Everybody was tense. Izuku smiled menacingly. "The Authenticity Of his words? Ahyuhyuhyu~! Well Eraserhead, should I tell or not?" Izuku asked cheerfully. Aizawa was sweating so much that a puddle was forming.

"The Jury has spoken. He's still planning on expelling some of us." Izuku finally said. Aizawa was now making a pool out of his own sweat. Shiki forced him to look at her.

Suddenly Aizawa was kneeling on a wooden board that had pieces of LEGO on it. Shiki was holding a giant cinderblock. She then put it on Aizawa's knees which made him howl in agony. "Lying is bad. You should keep your promises both in mind and body." She said.

She then went outside and grabbed another cinderblock which she totally didn't bring along and hide. "You should know that you have a lie detector in your class, so be careful." Shiki said and placed another cinderblock on him.

Everyone was very shocked and nervous. Shiki was well known for being a strict woman. And now they get to see it first-hand.

Then they all said. "This is going to be hell."
