Riko cares much for her team, but doesn't hesitate to submit them to killer-training. To motivate them, she often threatens to double, triple or even quadruple their training menus.[2][3] All in all, she is very determined for her team to win. As her job as the coach, she actually enjoys raising them up and bringing out the best in them.
She also sometimes tries to reward the team when they win, by giving them a kiss.[4] She tries to be cute, but the team doesn't buy it and it backfires. She likes cute things, as seen that she has mutliple pictures of puppies on her phone and is a big fan of Tetsuya #2. She can also get jealous easily, as she was irritated by Seirin's attention towards Momoi and even punished them for looking at her.[5
