Suiko is the oldest of three sisters in Cardfight!! Vanguard, alongside Rekka and Kourin. She works at their family cardshop PSY, where she's known for her calm, composed demeanor as she helps manage things behind the scenes. Fans often note her role as the steady presence keeping the shop running smoothly.
Beyond the shop, Suiko's a competitive player herself—she's part of Team Ultra-Rare and has made a mark in the competitive scene. She's best known for handing Aichi the powerful King Of Knights, Alfred card, a moment that stands out in the series as significant to his growth as a cardfighter.
