Something I like more than chupa chuls? There's no such thing! But... Well, if you do your best, Princess, that might change. Are you ready to become my number one~?

The other member of the two-man unit KitaKore. Like his partner, Ryuji grew up in a wealthy environment as well. He is witty and devilish in nature.


Standing 165 cm Ryuji is one of the shortest members of B-PROJECT. His hair is coloured deep purple with a part of his right bangs dyed pink. His eyes are a mix of his hair colours.

Ryuji has a petite build. In the game and anime he changes into different outfits. He likes to wear feminine clothes. Many of his costumes are figure-hugging while in his free time he often wears loose clothing as well.


At first glance, Ryuji seems distant but when he warms up to someone he becomes more friendly and open. Most of the time he hides his true feelings behind snarky comments but his heart is in the right place. He also likes to tease his friends. Tomohisa and Yuta, in return, like to tease him for his dishonesty.

Ryuji does not like to be called a girl just because of his preference for girlish things. When he is not satisfied with something, he tends to be moody or holes himself up in his room to brood over the problem. He works hard to be recognized as 'Korekuni Ryuji' and not as 'the son of famous actor Matsukura Kenzo'. 

When it comes to creative tasks, his mood lightens immediately, showing his passion for fashion and design.

His family is active in the show business. His father, Matsukura Kenzo, often is subject of various gossip magazines. The famous actor is said to have had many affairs. Because of his father's fame, Ryuji was bullied in the past. That is why he does his best to be acknowledged for his own achievements.

His mother is an actress and his older sister is a top stylist.[1]

When Ryuji first debuted and did not have a good experience from the workplace, he would go on to JOIN and complain. Now he has adjusted to it.[2]


Kitakado Tomohisa and Korekuni Ryuji are childhood friends. They first met at a party where they both sneaked out and played in the snow and built snowmen and snow bunnies.[3] Later on, both of them were enrolled in Bambi school, and by luck, they were placed in the same unit.

Both share a close bond and would meet up for meals. Ryuji would choose the place as Tomohisa has many places he wants to go to.[4] There are rare times when they take jobs separately. But if it happens, they are worried and think about the other's wellbeing. Though their concern for the other sometimes becomes a burden to their bond as they tend to hide their problems and deal with them on their own, much to the displeasure of their partner. In his SSR [BIRTHDAY PARTY] and the Season 2, Ep. 4 Tomohisa rather hid his negative feelings from Ryuji which caused a rift between the two. It becomes apparent that Ryuji wants his partner to be more open with him when it is about his worries since he also wants to help him solve those problems.[5][3]

In the issue of 2D☆STAR vol.3, Ryuji said if he was a girl it would be impossible to mingle with Tomohisa as their values are too different. But he didn't think anyone else would be his partner except for Tomohisa. The latter would choose Ryuji as his boyfriend if he was a woman. This shows that despite their difference in thinking and personalities they think of each other as irreplaceable.[4]

Even though both boys grew up in wealthy families their individual understanding of the common life differs greatly. Ryuji often has to correct or teach Tomohisa simple things.[6][4] He often is seen to sigh at the naivety of his childhood friend. He has an eye on Tomohisa's spendings since the latter tends to overestimate the cost of ordinary things like a train ticket. Season 2, Ep. 1 clearly states that Tomohisa wouldn't be able to survive without Ryuji because of his ignorance of many things.[7]

Moreover, Tomohisa likes to tease Ryuji about his occasional dishonesty which makes the latter blush in embarrassment. Nevertheless, both feel the most comfortable around each other's presence.

Ryuji and Kento are friends who exchange information regarding beauty. There was once where Kento bought a hair cream after hearing about it from Ryuji who had used it. [6]

Ryuji was one of the members that doubted Tsubasa’s capability when she was first introduced as their A&R. As someone who is critical of himself, he expects no less of others. His Kizuna story 1-3 and Season 1 depict well how he slowly warmed up to her and came to appreciate Tsubasa’s presence.[8][9]

Ryuji’s card stories are often about his love for sweets and fashion. After all the time they spent together she is prepared for the times when he is craving some sweets, hence she always carries his favorite lollipop with her. It also has become clear that he enjoys talking with her about fashion, even trusting her to pick out clothes for him at work.
Like Tomohisa, Ryuji enjoys picking presents for her, as a thanks for her support or just because he felt like it.[10][11] Tsubasa greatly admires Ryuji’s passion and the things he does to be at his best. Her genuine compliments often bring a blush to his cheeks but it is obvious that he is happy about them. Though, he makes her speechless as well with his flirty approaches sometimes.[12][13]

Another recurring theme is their mutual support of each other. Despite his harsh words, he tries to cheer her up in his own way. [12][14]
When she started out, she didn’t know yet how to respond to those comforting words hidden behind a rough tone but now, Tsubasa finds comfort in them, especially coming from Ryuji. And even though it is Ryuji who encourages her most of the time, Tsubasa too has a positive effect on him. The rare times he doubts himself or is unsure about something she is always there to give her honest opinion and shows him again what she thinks are his assets.[15][16]
