Valkyries are Obsessed with My Transformations! (Honkai Impact 3rd)

Transmigrated into the world of Honkai Impact 3rd, I awakened a transformation system that allows me to randomly turn into any character from HoYoverse. The first time, I transformed into Raiden Ei. I ended up calling Mei "Mother," all while acting shamelessly flirtatious with Theresa and Himeko. The second time, I shifted into Seele from Wildfire. I acted all annoyed with Bronya, calling her a "brat," yet I found myself instinctively reaching out to brush away her tears. The third time, I became Sündenjäger. I told Yae Sakura, "I'm nothing but a phantom," and yet I couldn't stop myself from staring at her in a daze. The fourth time... After every transformation, I’d have my fun and then vanish, keeping my true identity a total mystery. Or so I thought. Until one day— The way Mei looked at me started getting... complicated. Yae Sakura began "coincidentally" bumping into me everywhere. Even Bronya's cannons started aiming in my direction, seemingly by accident. I told myself, "There’s no way they know all those people were me..." System: [Abnormal affection levels detected from multiple characters. Suggestion for Host...] "Suggestion for what?" I asked. System: [Suggesting you start running. Fast.] — Description from novelcodex.org
