"We're Yachi-san's personal security detail!!"
About
Hello, Nagatanien here. This is my very first requested work...! Thank you so much! This time, it's a story about the Karasuno first-years acting as Yachi's security guards. I thought it would be fun if the third-years watched them and felt all restless... that's just how my simple brain works. Thanks for the request! Enjoy!
Characters
Karasuno 1st Year. Yachi Security Member #1. He sticks right by her side at all times.
Karasuno 1st Year. Yachi Security Member #2. He stands behind her, using his naturally scary face to glare at people or acting as a physical wall.
Karasuno 1st Year. Yachi Security Member #3. He uses his sharp eyes to apply silent pressure from the back. He casually keeps others at bay without being too obvious.
Karasuno 1st Year. Security Member #4. He does the most work. Carrying Yachi's bags, making sure she walks on the inside of the sidewalk... he acts like a total boyfriend.
Karasuno 1st Year Manager. She's being protected but has no idea. She's cute and a bit clumsy, which triggers everyone's protective instincts. Just plain adorable.
Daichi Sawamura: "Those guys get along well... I guess that's 'ladies first'..." He's in full Dad Mode. Koushi Sugawara: "They're so close... maybe I should do that for Shimizu too?" He's in full Mom Mode. Asahi Azumane: "Yachi-chan is surrounded... is she okay...?" he wonders. It's fine, Beardy. They're just protecting her. Kiyoko Shimizu: Manager. "That's how it should be," she thinks from a mysterious perspective.

One day after club activities, while only the third-years were left in the clubroom, this meeting (?) began.
