Chihaya chooses to go on her class trip in hopes to come closer to fulfilling her dream of being a teacher, but she spends the entire time lost in space, wondering how Taichi is doing at the Master tournament qualifiers. Harada and Inokuma are also participating in the East Japan qualifiers, but as Taichi tries to quietly psych himself up, someone unexpected shows up to get in his way. Meanwhile, at the West Japan qualifiers, Master Suo makes a surprising comment to Arata.

The veteran players Dr. Harada and Inokuma were the winners in the first round, but Dr. Harada chose to yield the second round to preserve his strength for the third. Arata starts to feel sucked into Dr. Harada's pace, but after receiving some advice from Chihaya, he remembers how his grandpa, the Eternal Master, used to play. Both of them enter the third round with one win and one loss as the battle to determine who will challenge the Master begins!

Both the Master and Queen matches come down to luck of the draw in an intense first round, ending in wins for Shinobu and Harada. Shinobu is shaken after learning that her grandmother, a politician, sees her as no more than a walking advertisement, as well as the fact that Chihaya chose her class trip over a chance to play in the Queen match, and she begins to break down in the second round.
