It's the day of the Master and Queen challenger finals. Dr. Harada and Arata are competing for the chance to challenge the master, while Inokuma and Megumu battle it out to challenge the Queen. Harada confides in Arata that he once played against his grandfather, Eternal Master Wataya Hajime, and expresses his joy at being able to play karuta with Arata. A passionate battle spanning multiple generations begins at last!
Not sure, but I heard something happened

algo muito tenso entre eles no passado.
Не знаю. Но слышал, что
в прошлом между ними кошка пробежала.
