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!
What worries me is that he might have 
done too much research on Wataya-kun.
ما يقلقني هو لعلّنا تحرّينا كثيراً عن واتايا-كن
Mich besorgt aber, dass er sich zu viel
mit Wataya-kun beschäftigt hat.
Lo que me preocupa es que quizás
investigamos mucho a Wataya-kun.

Je m’inquiète. Aurait-il trop étudié
le style d’Arata Wataya ?
Ciò che mi preoccupa, però,
O que me preocupa é que ele pesquisou 
demais sobre o Wataya-kun.
Меня беспокоит, что мы могли слишком
зациклиться на изучении Ватаи.
