I Transform at Random, and Every Valkyrie Wants to Cuddle with Me!

After transmigrating into Honkai Impact 3rd, she awakens the Transformation System, which lets her randomly turn into any character from a MiHoYo game. The first time, she turns into Raiden Ei and calls out to Mei, "Mom!" The second time, she turns into Hellfire Seele and dismisses Bronya as "some little brat," yet instinctively helps wipe away her tears. The third time, she turns into Original Sin Hunter and tells Yae Sakura, "I'm just an illusion," but keeps staring at her in a daze. The fourth time... After transforming, she shows off, leaves the Valkyries emotionally scarred, then runs off without taking credit for her deeds.
