While working with Chrono in setting up for a Vanguard tournament for children, Tokoha reunites with a woman named Akane Kiyosu. The two have known each other since their youth and have a sister-like bond, but they have grown distant as time passed. One day, when they were young, Tokoha and Akane buried a time capsule in a park; they both put one present into the capsule that they kept secret from each other to this day. When Tokoha sees that the same park is now undergoing construction, she learns that Chrono had dug up the capsule as part of a quest from Akane, who then takes that capsule. Tokoha later learns and is distraught from the news that Akane has taken a post overseas and will be leaving Japan tomorrow.
The next day, during the children's Vanguard tournament, Tokoha resolves to see Akane at the airport and have one more cardfight with her as a farewell gift. As they both recall their memories from the past, Akane reassures Tokoha that her departure is not the end but rather a new beginning. After Tokoha wins the fight, Akane gives her the present that she placed in the time capsule: a gold medal. Akane then leaves, and while on the plane, she opens the gift that Tokoha had left in the capsule: a special card of herself drawn by a young Tokoha.
