Kaga Kusha is a male student who attends Akademi High School. He is the president of the Science Club.


Kaga has messy, silver hair fading to blue like a stereotypical mad scientist. He also has light blue eyes with a blue eyepiece over his left eye.

Kaga wears a long, white lab coat with a slit in the back and gold rubber gloves over the default male uniform. He wears the "Red Armband of Leadership" with a picture of an Erlenmeyer flask on his left arm.

"This year, the Science Club is led by Kaga Kusha, a brilliant young inventor who has already contributed meaningfully to several fields of science, most notably in the field of "smart glasses" and other optical head-mounted displays. Every member of the Science Club is wearing a head-mounted display that was built by Kaga, and custom-tailored to their exact needs."


"The most intelligent - and eccentric - student at Akademi. Possesses a genius-level IQ, but is prone to extremely bizarre behavior, and frequently expresses thoughts that frighten and concern the people around him."

Among the personas currently implemented in the game, he is a Teacher's Pet. He will give Ayano a suspicious look if she aims her camera at him. If he sees a corpse or witnesses a murder, he will run to tell a teacher, unless another Teacher's Pet already has. He cannot participate in physical fights against murderers. Kaga's IQ is 170.[4]

"Kaga is the most intelligent - and most eccentric - student in Akademi High. He was reading by age 2, writing by age 4, could speak multiple languages by age 6, demonstrated a genius-level IQ by age 8, and passed multiple college-level proficiency tests before age 10. Despite his genius, he is not a well-liked figure at Akademi High; he is prone to extremely bizarre behavior and frequently expresses thoughts that frighten and concern the people around him.

He will openly speak of his aspirations for "world domination" to anyone that is willing to listen, although he refuses to divulge the specifics of his master plan. It is common knowledge that he has a deep obsession with Saikou Corporation, the most powerful business conglomerate in Japan. He has openly stated that he fully intends to become the CEO of Saikou Corp as soon as possible - but he never divulges how he intends to do so. Additionally, he also seems to be obsessed with the concept of constructing a giant robot.

He could have easily gotten into a top university, but instead chose to enroll in Akademi High School, stating that it is "the first step" towards his ultimate ambitions. Many students have observed him studying the school's Student Council President, Megami Saikou, in a way that borders on stalking. His behavior can only be tolerated by other individuals who are almost as eccentric as he is, and so his club has come to be populated almost entirely by Akademi High's most unusual students."[5]


At 7:00 AM, Kaga enters the school grounds. He walks to his locker at 7:05 AM and changes from his outdoor shoes to his indoor shoes. At 7:15 AM, he walks to the Science Club on the third floor and looks at a screen.

At 8:00 AM, he walks to Classroom 3-2 and sits at his desk. He starts his morning classes at 8:30 AM, and leaves to go to the outside of the Science Club to eat his lunch at 1:00 PM.

He walks back to class again at 1:30 PM and participates in cleaning time between 3:30 PM and 4:00 PM. Afterwards, he heads to the Science Club and stays there until the end of the day.


Kaga's parents are very, very similar to him. His father works at Saikou Corp developing artificial intelligence, and his mother works at Saikou Corp in the robotics division.[6] Once they realized that Kaga was a prodigy, they did absolutely everything possible to help him develop his intelligence further.[7]

Welcome...to my lair! I, I mean...the Science Club. What do you seek?
— Speaking to him while he is inside the Science Club.
I shall await your return.
— Leaving the conversation while he's inside the clubroom.
There is nothing more powerful than science and technology! He who can master both...will rule the earth! Nya ha ha ha ha ha ha haaaaa! Our pursuit is the development of a new technology for the purpose of world domin -I mean...the betterment of mankind. If you join this club, you'll get access to our robot army! ...right now, that's just a cleaning robot - but hey, we gotta start somewhere.
— Asking him more information about his club.
You want to join? Splendid! You'll be a fine test subj - I mean...clubmember.
— Asking to join his club.
Eeeeexcellent. Hmm hmm hmm hmm he ha ha ha ha, AH HA HA HA HA HA HA HA, AH HA HA HA HA HAAAAA! Eh - eh - hrm...sorry.
— Joining his club.
You may have escaped today, but you haven't seen the last of me!
— Refusing to join his club.
Are you attempting to stage a daring escape from our club?
— Asking to leave.
Of course you won't leave. None can escape my grasp. Hmm hmm hmmmmm!
— Deciding against leaving the club.
Tsk tsk! What a pity. This will set our plans back for months, if not years! Curses...foiled again!
— Leaving the club.
Unfortunately, you may not be permitted to return. An unpredictable variable such as yourself would...endanger my plans.
— Trying to rejoin the club once more.
We're still making preparations. The last time we conducted an experiment without proper precautions, the results were...um, hmm hmm...explosive. Come back between 5:00 and 5:30!
— Trying to participate in club activities too early.
Time waits for no man! And neither does science! The experiment is already over. Try to make it here before 5:30 next time!
— Trying to participate in club activities too late.
Are you ready to DO SCIENCE?
— Asking to participate in club activities.
There's no time to waste! Let us begin!
— Agreeing to participate in club activities.
You have until 5:30. Then, we start without you.
— Deciding not to participate in club activities.
Go away! Or my latest invention will use you for target practice!
— If Ayano attempts to join his club after he has seen her commit murder.
Your recent conduct is quite unbecoming of a scientist! I cannot allow you to besmirch our good name! I must remove you from this club. Hmph!
— If Ayano is kicked out of the club due to a member witnessing murder.
One of my colleagues cannot concentrate when you are around. To prevent a drop in productivity, I cannot allow you to join this club. It's simple logic.
— If Ayano attempts to join his club when a member saw her connected to a murder.
You wish to be in two clubs at the same time? Ooh, how bold! However, I simply cannot allow it! You have to leave the other club in order to join us. Hmph!
— Trying to join this club when Ayano is already a member of another club.
Another one... hmph, a minor setback, no matter. After all... it's not like we have a shortage.
— Kaga in "March Progress Report".
Ahhhhh! The student council president herself honors me with her presence? My calculations determined that it was only a matter of time until you recognized my brilliance and willingly submitted yourself to my -
You're saying that my acoustic-quieting noise-mitigators have failed to properly suppress the reverberations of my experiments? Blast it all! I must have miscalculated...
I assure you that, within the day, this room will be capable of containing a kiloton explosion without detection by a seismograph! No, a megaton! No, a gigaton! Why stop there? A teraton!
An exaton, a zetton, a YOTTATON!
Financial restrictions?! My One True Enemy! ...besides the lack of raw materials required to build a Dyson Sphere. That is my other One True Enemy.
It's for the best. After all, I haven't finished synthesizing the engagement ring yet.
You'll see! Ee hee hee hee...Aa ha ha ha...MWA HA HA HA HAAAAA!
— Hypothetical dialogue of Kaga speaking to Megami Saikou.[12]
While your proposal may be mathematically sound, you're forgetting different clubs have different needs. The Science Club, for example, needs $200 to rebuild the flux capacitor that was damaged by the explosion of the temporal field capacitor last week.
— Hypothetical dialogue of Kaga during a club leader meeting.[13]
Love? That's just the word for when your brain commands your amygdala to release endorphins, oxytocin, vasopressin, and dopamine to your limbic system whenever you think of a specific individual, in order to increase the possibility that you will take action to court that individual, in order to increase the possibility that you will reproduce with that individual, which is the purpose of all biological life. But, to answer your question: No. Nobody I've ever encountered has been worthy enough to stimulate my amygdala into releasing endorphins!
— Hypothetical dialogue of Kaga answering if he has ever fallen in love.[14]
