Missing: History.

In the daytime it's hard to get his engine going, so Ritsu is often found napping in all sorts of places. He goes at his own pace and is relaxed, but can say some cutting things when he thinks quickly. His singing voice is like a sweet whisper, and his performances flow languidly.

A member of NEW DIMENSION’s Knights.[1]

I’m Ritsu Sakuma of New Dimension, and I belong to the unit Knights. As a knight, I’ll show our princesses the most wonderful dreams...♪ Well, it’s true I’ve been in the public eye because I’m that Rei Sakuma’s younger brother, but I’m determined to be remembered as my own person. If you’re going to support me, I’ll meet your expectations in my own way. Fuaaa… This is good enough for a self-intro, right? Well then, thanks for your support~♪[1]

The members of Knights are all pretty strange, but somehow I get along with Kuma-kun? Maybe because he’s like a shadow? Being near him doesn’t bother me, and he’s always been there for me. However, Kuma-kun’ll disappear before you know it, since he’s a friend who keeps his distance… But you know, I think the distance between us has closed a little bit recently? I think going forward, it’s time for Kuma-kun to come out of the shadows and shine in the light too.[1]

Ensemble Stars! Introduction

Ritsu always sounds sleepy and languid. Nocturnal and loves sleeping, he can be found napping anywhere. He had to repeat a year due to too much tardiness and dozing off in class, but he doesn't care.

Childhood friends with second year Mao Isara; they know each other very well. Even though he's older, Mao is actually the one taking care of him. Third year Rei Sakuma is his older brother, but he has a rather brusque attitude towards Rei. He hates getting involved with people. A member of the unit Knights.[2]


Ritsu has mid-length black hair with bangs and side bangs that frame his cheeks. He has a tiny speck of hair and a stray bang sticking out of his head. He has red eyes and a fair complexion. At school, he wears his school blazer unbuttoned over his gray sweater. His white shirt is untucked with a messy collar. He wears brown dress shoes and loose plaid pants.

On stage as a member of the unit Knights, Ritsu wears a dark blue coat with white sleeves and a ruffled tailcoat over a white shirt. There’s a vertical blue line on his sleeves. The sleeves have a blue cuff, with a gold accent to them. His white shirt has a black vertical line in the middle, accented with gold. His shirt collar is blue, accented with gold as well. On the shirt’s collar, there are swirly gold patterns. Where the buttons would usually be, are golden frog closures. On his jacket there are black epaulettes. The rope on the epaulettes are golden. From his left epaulette are two golden strings, which lead to a blue banner with the fleur de lis symbol on it which is pinned on the right side of his chest. On the back, he wears a cape which is blue on the top end and white on the underside. There is a golden accent on the blue half of the cape. His pants are dark gray, with light gray vertical lines on them. He wears a thick belt with four golden buttons on them. There are golden lines on the side of his belt. Attached to the belt are two golden ropes. His boots are white, with the tip and the bottom being black. There is a black vertical line going down the shoe, with gold shoelaces. Under the shoelace tie are two black belts with a straight vertical gold buckle. Ritsu wears black fingerless gloves.

Ensemble Stars! Appearance

Ritsu has mid-length black hair with bangs and side bangs that frame his cheeks. He has a tiny speck of hair and a stray bang sticking out of his head. He has red eyes and a fair complexion. At school, he wears his school blazer unbuttoned over his gray sweater. His white shirt is untucked with a messy collar. He wears brown dress shoes and loose plaid pants.

On stage as one of the Knights, Ritsu wears a navy blue, white, and gold jacket resembling a royal military uniform over a black shirt. He wears black fingerless gloves with a golden stripe on the side. On the jacket, there are four thin golden ropes attached to the collar, two connecting to the right shoulder pad and the back of the jacket while the other two are left hanging with knots in the front of the jacket. There are also two golden ropes which hang from the bottom left of the front to the back of the jacket. There is a navy blue and white stripe patterned sash connecting from his left shoulder pad to the bottom right of his jacket. He wears black combat boots with gold-colored laces and buckles on the top part of the boots.


Though he may seem cold and uninterested, Ritsu is a playful and intelligent person at his core. Energy isn't something that comes naturally to him, and he is instead quietly passionate, and likes to tease others, enjoying their reactions.

At the start of the year, Ritsu tended to distance himself from his classmates and idol activities, which he viewed as laborious and boring because of the previous fractured state of knights. He was reluctant to make friends due to this (Mao also insinuates he has social anxiety issues). But as the year goes on, Ritsu begins to open up and form important bonds with his friends and unitmates. He is very loyal and affectionate to the select few he is truly comfortable with.

Ritsu can be blunt and harsh to a fault, but is very intuitive and often picks up on others' emotions. He regards psychoanalysis as a 'bad habit' of his, yet is very adept at it. At times, he be very clingy, and loves it when others praise him. He can be violent, especially towards his older brother, and doesn't hold his tongue often. Despite this, he can get very protective of his loved ones, to the point of being possessive.

Ritsu has abandonment issues largely stemming from Rei's absence last year, which contributes to his tendency of clinging to those he truly loves, yet also his habit of distancing himself from others as a whole. He shares Rei's aversion of sunlight, and becomes more active and 'alive' at night. They also share a habit of jokingly regarding themselves as older and wiser than their juniors.

He loves music, and plays the piano. His songwriting reveals a much deeper and more wistful side of him, something that he almost never reveals to others, preferring his smug and sleepy persona. Somewhat surprisingly, though, he tends to keep things to himself to avoid burdening others. As it stands, Ritsu values his unit and friends very much, and is willing to put effort into his idol work (or at least that which interests him).


Ritsu's name 凛月 means "cold moon". “Saku” (朔) in his last name refers to the first day of the lunar month, which begins with a new moon. “Ma” (間) refers to an “interval of time”.


  • Ritsu's autograph consists of only his first name, rendered in Roman letters.
  • Ritsu had to repeat his first year as he's often late for class or sleeps during class, ruining his attendance record.
  • Ritsu has low blood pressure.
  • Ritsu serves as Knights' strategist.
  • Despite how strange (and disgusting) his pastries look, they actually are delicious. Rei seems to say that Ritsu has a bright future for "Grasping the concept of black magic at a young age" because of the pastries, much to Ritsu's delight.

Voice Actor Comment

"Each character has their own very unique personality, and I was very conscious of trying to draw out his charming points as best as I could during the recording sessions. During daytime, he always appears lethargic, not wanting to have anything to do with other people, and somewhat distant, but I wonder if it's not simply because he doesn't quite understand interpersonal communication, and maybe he's bewildered, not knowing what he should do.

Thus, I would be very happy if the players would look beyond his aloofness and notice the straightforwardness and childishness hidden inside. He's very honest about his feelings, and I mean this in a good way, so I hope you will regard him from the point of view of an adult." (Enstars!)
