Before the February 15th, 2016 Build, he had orange hair. His eyes were orange as well. Juku's hair was a mirrored and recolored version of Riku Soma's hair with tufts jutting out from the left side.
As of the February 15th, 2016 Build, his hair is very similar to Senpai's default hair, but with hair tufts on both sides.
He wears a white headband with Japanese symbols on it. If the club disbands, he will not wear the headband anymore.
When in the Martial Arts Club, he will don a traditional sparring outfit.
He was previously a Hero, but he is currently a Teacher's Pet as of the January 1st, 2016 Build. If he sees a corpse or witnesses a murder, he will report to his teacher, unless another Teacher's Pet already has.
At 7:05 AM, Juku enters the school grounds. He walks to his locker at 7:10 AM and changes from his outdoor shoes to his indoor shoes. At 7:15 AM, he walks to the Martial Arts Club on the second floor.
At 8:00 AM, Juku walks into Classroom 1-2 and sits at his desk. He starts his morning classes at 8:30 AM, and leaves to go back to the Martial Arts Club at 1:00 PM.
Juku walks back to class again at 1:30 PM and finishes his afternoon classes at 3:30 PM. Afterwards, he heads to the Martial Arts Club and stays there until the end of the day. If the player joins in club activities, he practices kicking with the other members from 5:30 PM to 6:00 PM.
If the Martial Arts Club is inactive, he will socialize with the other former members outside of the club during periods when he would normally attend it (7:15 AM, 1:00 PM, and 3:30 PM).
- He is an apprentice-level disciple of Budo Masuta, as said in his Student Profile.
- He was implemented in the November 15th, 2015 Build.
- His name is a play on words. Jukuren (熟練) in Japanese can mean either "skilled" or "proficient", although this does not reflect Juku's self-defense level, which is "very weak".
- However it actually originated from jukuren shita shokunin (熟練した職人), meaning "journeyman", which is a reference to someone who is learning something.
- On the January 1st, 2016 Build, his persona changed from Heroic to Teacher's Pet.
- He is the only student in the Martial Arts Club who does not have the Heroic persona. He is also the only Teacher's Pet who can defend himself.
- His female counterpart is Shima Shita.
