He is loved by everyone in REBORN as someone who adds a gentle and gorgeous color to IS:SUE's intense performance.♪
Here, we would like to introduce some comments received from everyone at REBORN.
- 📢Rin-chan's charm is her visuals, voice, and stoic attitude. Her cute yet mature and beautiful face goes well with any styling and brings out Rin's unique atmosphere.

Even when the odds were against him, he never gave up, faced the lessons single-mindedly, and continued to make efforts.
His upright attitude touches the hearts of many viewers and gathers voices of support.
At the first ranking announcement ceremony, it ranked 11th.🏆
He quickly rose to within the debut range and made it all the way to the final round, showing a truly ``low-knock-out'' development.
Even after his debut, his uncompromising attitude toward training remains the same.
