Sayaka Sasayama

Sayaka Sasayama (サヤカ Sasayama Sayaka) is a character in the Yu-Gi-Oh! ARC-V anime. She is a friend of Allen Kozuki and is a surviving resident of the Xyz Dimension as well as one of few remaining members of Resistance.

Appearance
Sayaka is a bespectacled young girl with blue eyes and short light-purple and lilac hair that is restrained by light green and orange hair clips that resemble bicycle helmets. Sayaka wears a light blue dress with a teal turtleneck under a tan dress held up with brown shoulder straps and a blue belt that has a golden symbol resembling twin birds back to-back and green and orange punches at both hips. She also wears brown tights, blue boots, and white gloves.

Personality
Sayaka has shown herself to be kind and caring; handing out soup rations to people despite not being on shift at the time. Allen claims that Sayaka is quite shy.

Past
Before Academia's invasion, Sayaka, together with Allen and Kaito Tenjō, were students of Heartland Duel School's Clover Branch who studied under Yūshō's guidance, who was the teacher of their branch. She is also Ruri's close friend despite the rivalry of their Branch, often having a friendly Duel and hanging out together. She was the one who told Ruri about Yūshō's philosophy to bring smiles with Duels. One day, Academia attacked and nearly annihilated the entire population of Heartland City. During this invasion, Yūshō suddenly disappeared, leading them to believe that Yūshō had abandoned them. One night after the first Academia attack, Sayaka witnessed Ruri being kidnapped by Yūri, and since then blamed herself for unable to do anything to save her.

While Shun and Yūto went to Standard Dimension to look for Reiji, the Resistance continued to fight. Despite their best efforts, both Spade and Clover branches were nearly wiped out, forcing them to be in hiding.

Yūya vs. Kaito
Sayaka and Allen were reunited with Shun, who got transported back to Heartland along with Yūya, Gongenzaka, and Shingo. The three of them then looked for Yūya and the others, arriving just in time to stop the Duel between Kaito and Yūya. Together with Shun and Allen, she assured Kaito that Yūya and the others are a few allies that Shun brought with him to help them. Sayaka asked Kaito to return and fight together with them again, but Kaito refused and left the scene.

Resistance Hideout
Back at their hideout, Sayaka helped in distributing foods for the refugees even though it's not her shift. Allen told her not to overwork herself and told her to rest, something that Sayaka reluctantly relented. Sayaka then listened to their discussion and revealed that Kaito's entire family had been carded by Academia while Shun and Yūto were away. While Yūya was lamenting over this, she remembered Yūya's last name and asked does he has any connection with Yūshō, explaining that Yūshō was their teacher and disappeared during the invasion, and Allen believed that Yūshō has abandoned them.

Shun vs. Kaito
Sayaka and Allen arrived just as Kaito turned another group of Academia Duelists into cards. She and Allen tried to convince Kaito to stop fighting alone and return to them, but Kaito remained adamant on his decision to fight alone as he now believed that allies and such are nothing but a burden. Shun decided to Duel Kaito, hoping to open his heart once more. As the Duel went on, Sayaka noticed the change in Shun's heart and like everyone else was surprised when Yūya revealed that Yūto is inside him. When Shun lost the Duel and was about to be turned into card by Kaito, Sayaka interrupted and revealed that she had witnessed Ruri's abduction and blamed herself since then, prompting Kaito to leave.
