Shine the Light Piltz visits Teru to check on her health after her fight with Stardust. Teru asks her to use her healing power on the back of an elderly, widowed caretaker of a stationery shop, Chihiro Nagata, whom Teru has known since childhood. All three women end up going on a mountain hiking trip, despite this not being an activity that Piltz is particularly fond of. Upon reaching the summit, Teru learns about Piltz's upbringing in a mountainous region, where she had both her legs amputated as a kid after an accident. After the trip, Teru returns home to practice drawing out her flames, but to no avail. A girl invites Teru to the school's calligraphy club, where she has an epiphany about how to control her power. Through putting all of her heart in writing calligraphy, Teru finally learns the method of channeling her flames.
