Miya Chinen/Relationships

### Reki Kyan

Reki and Miya had a rocky start with lots of mutual hostility at first where Miya refers to Reki as 'Slime', displaying his obvious scorn and deeming him an unworthy opponent. After the loss against Langa Hasegawa, Reki befriends him, assuring that they won't abandon him like Miya's old friends did. Reki jumps to his defense against Adam; when he was disparaging him. Reki challenges Adam to a beef as he tries to protect his new friends' pride, despite others telling him it would be impossible to win. He was quick to offer tips to Reki on ways to go against Adam and gives him advice on how to improve his lifestyle. But in Episode 5, after Reki's loss, Miya starts calling him 'Golem' as an upgrade, subtly showing that his respect for Reki had expanded. In Episode 7, Miya shows concern for Reki after his actions became 'UnReki-like' and questioned where he was to Langa. He teases Reki, but equally cares for him as Reki cares for Miya.

### Langa Hasegawa

Miya and Langa befriend each other through Reki Kyan where they both follow Reki's antics like getting into Hiromi Higa's car, teasing Hiromi and the teasing of each other. They seem to respect each other on a competitive level. He races against Miya as a test run, but the straps on his skateboard break and he falls.

Miya tells him scornfully that he should get a better rig for the real race, so that Langa couldn't blame his "defeat" on the board. During the real 'S' race, Langa is visibly impressed by his skills, and likewise Miya acknowledges Langa's raw talent as he skates.

### Ainosuke Shindo

During the race with Langa Hasegawa, Miya comments on how Adam was the one who prompted him to skate against the other, although thinking it a waste of skill. Miya is more or less afraid of Adam and his words damages his mental state, which leads to Reki challenging Adam to defend Miya. It is shown that Adam has been around Miya for a period of time, giving him tips on how to become stronger. Miya regards these tips as "on point", and helped him excel quickly. Adam arrives after he loses, saying how Miya has nothing anymore, no friends, no skating skills; manipulating his brain. Before Reki Kyan starts the beef in Episode 4, Miya tries to get him to opt out of the race, even reluctantly saying that he was an "empty shell". Miya is seen much more relaxed and excited when separated from Adam and with Reki and Langa. Adam and Miya finally skated together for the first time during the tournament qualifiers, and Miya was dismayed to see that Adam was so far ahead of him. Miya expressed horror when he watched on as Ainosuke brutally beat Reki during their race.

### Hiromi Higa

Miya joins Reki Kyan and Langa Hasegawa in using Hiromi for transportation. Miya threatens to tell his manager at the flower shop he works at, so he gives in and agrees to go with them. They also used her as a way to manipulate Hiromi to come on the trip with them. He seems to enjoy teasing and tormenting Hiromi for humor.

### Kaoru Sakurayashiki

Miya finds some of Kaoru's habits during Episode 6 strange like using an umbrella on the way to the beach. Then while they were on the beach, he refers to Kaoru as 'Mom', playing with his slender form and attractive appearance to distract Kojiro Nanjo from the girls.

Despite that, Miya seems to show respect for Kaoru. When Cherry's race against Adam was going to start in Episode 9, Shadow said to make a bet on who would win and Miya immediately said Cherry with a straight face, despite knowing and interacting with Adam for the longest time. Showing that Miya was confident that Cherry could defeat an opponent like Adam.

### Kojiro Nanjo

Miya refers to Kojiro as 'Dad' during Episode 6 to get him to stop talking to girls. He played into the role of a young son and jumps on him to exaggerate their "father-son relationship". Miya has taken a liking to mess with Kojiro's love life by directing him towards Kaoru Sakurayashiki and causing confusion for the women he was flirting to.

Miya became concerned for Joe in Episode 8 when he was going at dangerous speed against Langa Hasegawa and was shocked when he was left unharmed after he made a move that should break his leg.
