Birth - S1.E37

Erin officially becomes a Master in the fall and new students come to Kazalm. But Shiron, a female student, sees Erin as an enemy and desired to "beat her." When Shiron decides to approach Lilan one night, she is astonished to find out that Erin can embrace Lilan so closely, despite the fact that Ohju never befriend humans. When Shiron decides to approach Lilan again, she ends up angering Lilan, only to be saved by Erin. Shiron then witnesses Erin helping Lilan give birth, and has a new perspective of Erin, making Shiron decide to be Erin's follower. The Shin-Oh names the baby "Aru" and decides to visit the baby.
