Anime Crossover: They Keep Building an Invincible Persona for Me

The title Lin Yi came up with:

I'm strong. Why don't you believe me? I'm invincible in this world, but since I'm stuck in a slice-of-life anime, the girls call me a chuunibyou! I, Lin Yi, am invincible in this world. Why should I explain myself to anyone? Stupid mortals can't understand what it means to be a god!

The titles the slice-of-life heroines came up with:

My Big Brother Is Actually a Severe Chuunibyou! The Student Council President Has Started Another Chuunibyou Day! The Nth Day of Curing His Chuunibyou! He's a Chuunibyou, but he's Super Lucky! How a Severe Chuunibyou Saved the World!

Then one day,

Lin Yi overuses his abilities, causing the slice-of-life world to collapse and a series of battle-manga worlds to appear.

The slice-of-life heroines undergo a complete 180-degree change!

The slice-of-life heroines: "If we want to survive, we absolutely cannot let him fight!"

Lin Yi: "I'm obviously super strong, but they never let me fight!!"
