Meanwhile, at the West Japan qualifiers, Master Suo makes a surprising comment to Arata.

Taichi has seemed down since he lost to Arata. In fact, a dark cloud is hanging over the entire karuta club because final exams are coming up. To break out of the gloom, Chihaya, Kanade, and Sumire decide to make Valentine's Day chocolates for the club as a surprise. Chihaya has no experience with making sweets, but she gives it her all in hopes of bringing a smile back to the hard-working Taichi's face.
