Yu-Gi-Oh! SEVENS: Tiadosia Kallister

She's Luke's/Lucidien's older sister. She's the president of the Music Club at Goha 7th Elementary. She is a hot-blooded duelist who uses Wind-type monsters called Music Maidens with her Music deck based on martial arts and woodwinds. She is a skilled fighter without her duel disk and deliberately sought out the mastery of woodwinds in order to improve her breathing abilities. Her brother is afraid of her due to how loud she can be and send him flying with the sound of her loud voice if she gets infuriated by his stupidity and if anyone called by her real name instead of Tiger. This is from Episode 48 where she and her childhood friend, Asana, were looking for Luke after he was gone missing in a snowstorm which led to a misunderstanding over her thinking she was abandoned when looking for Luke as Asana and her great-grandfather had stumbled upon the half-frozen Kayama and Hatrap (Kayama's pigeon friend) and took them to the hospital-leads to her seeking vengeance.
