Ryūji Kanzaki

Ryūji Kanzaki is one of the students of class 1-B.

Appearance
Ryūji is a young man of average height with violet-bluish coloured hair and purple eyes.

Personality
Not much is known about Ryūji but he appears to be a diligent student who carries off a serious manner. He is a very helpful person, as shown when he aided Honami Ichinose in the case of Ken Sudō.

He is friendly as he sat with Honami to talk after the survival test and shared a laugh with her about how their class lost after coming second.

Intellectual Abilities
As a student of B-Class, he is very intelligent as he recognized the fact that three boys from C-Class could have overpowered Sudō since they were delinquents or athletes.

These were excellent deductions as his theory was proven to be correct as the attack was a set up to frame Sudō to get him expelled.

Plot
Ryūji is first introduced in his class, as their teacher Chie Hoshinomiya announced their class grades after a quiz. Later on, he is asked by Honami to help D-Class prove the innocence of Ken Sudo, Ryūji agreed and put up flyers for those who know anything. She later brought him along to meet Kiyotaka Ayanokōji who saw the flyers and mentioned it was Ryūji's idea. When Honami got alert, he was intrigued as they obtained information about Daichi Ishizaki as Ryūji saw holes in C-Class' story making a theory about it being a set-up. He leaves with Honami who promises Kiyotaka that she'd provide more information to him if they find some.

During the survival test, he and Honami go to C-Class' camp but found it deserted. They were joined by Kiyotaka and Airi who were scouting the forest, but ended up at the beach. Ryūji asked Kiyotaka if he was scouting as well but the latter replied it was just by chance as Honami bemoaned the fact that she didn't get the chance to discover C-Class' leader. Ryūji told her what the purpose of the test is, as she agreed with him. When Kiyotaka asked Honami about Kōhei Katsuragi both she and Ryūji informed him of his status as one of A-Class' leaders besides Arisu Sakayanagi, even detailing how there appeared to be a leadership conflict between the pair.

On the final day of the test, B-Class chose not to guess the leaders of the other camps since their bonus points will be negated if they are wrong. When the results were given, B-Class was in second place while D-Class is in first leaving C-Class in last place and A-Class in third place. Ryūji was surprised at these results along with the rest of his class.

After returning to the cruise ship, Ryūji sat with Honami and they talked about the survival test. Honami happily stated that it was their class' lost even if it was second place, something he agreed with. She soon changed the topic by questioning him over what they were told about points and how they could decide on what to do with them as he pondered on her question.

Ryūji is seen with class celebrating the class point result after the Paper Shuffle test.
