Description
Suiko Tatsunagi, the eldest Tatsunagi sister alongside Rekka and Kourin, operates the cardshop PSY and performs in the pop idol group Team Ultra-Rare. Her surname, combining "standing" and "calm, lull," reflects her usually composed, settled nature as a facilitator. She possesses the unique ability to perceive events on both the planet Cray and the planet Brandt, guiding her actions. Suiko senses potential for PSYQualia in others and manipulates events to cultivate it, heavily implied to have instigated Ren Suzugamori's initial acquisition of PSYQualia. This act fractured his friendship with Kai and Tetsu a year before the main events. Later, she presents Aichi Sendou with a pivotal choice between a "card of light" and a "card of darkness"; his hesitation unexpectedly forms Majesty Lord Blaster.
During the Vanguard Circuit, Suiko and her sisters adopt Angel Feather decks to match their idol image. Suiko's deck focuses on the Pegasus series and Chief Nurse, Shamsiel, employing defensive strategies that manipulate the damage zone. In Season 3, under Takuto Tatsunagi's direction, she attends Fukuhara High School. There, she displays rare anger toward Naoki Ishida over his remarks about her sailor uniform, sparking intense cardfight rivalries. She initially defeats Naoki but later loses a rematch and acknowledges his growth.
Suiko becomes Reversed after switching to a Link Joker deck, serving as a tertiary antagonist. Influenced by this state, she transforms Minami Kawanami and Asaka Narumi into PSYQualia Zombies and battles Ren Suzugamori, losing to his Raging Form Dragon. Freed from Reversal by Kouji Ibuki, her connection to Vanguard severs, leaving her emotionally detached yet continuing to serve the Destiny Conductor. As a Called Walker, she is eventually erased from collective memory.
In the manga continuity, a flashback reveals Suiko's role in triggering Ren's initial descent into PSYQualia obsession during a cardfight, directly causing the rift with Kai and Tetsu. She also appears in the spin-off *Cardfight!! Vanguard Extra Story -IF-*, transported alongside Kouji Ibuki to an alternate world without cardfighting. There, she allies with Emi Sendou and the fairy Shuka as the "Blaster Pair" to combat Jammer's minions.
Fan interpretations frequently emphasize her moral ambiguity and manipulative tactics, drawing parallels to Kyubey from *Puella Magi Madoka Magica* for her unsettling expressions and utilitarian approach to power.
