"So why was I playing Shadowverse before, but ended up transmigrating to the world of Princess Connect?"
"There's no evidence that you have to transmigrate into the game you were playing beforehand, so this is perfectly normal. Anything else you want to ask?"

This book includes, but is not limited to, the crossover memes: Handshake Overlord, DDK, 'Ba Tong Qi-chan Says,' 'How Do You Counter Shizuru Playing a Four-Cost Move on the Draw?', 'Xcw's Yui Is the Yui in Kimura Yuito,' 'May Anyone Who Urges People to Play szb Be Struck by Lightning,' 'Yali Sha Is Still Missing Today,' and 'In the Jin Taiyuan era, Yali Sha made a living by fishing,' among others. The timeline is generally close to the game. It's a slice-of-life fanfic. That's all.
