Anime Crossover: I Help Others for Fun, and They All Call Me Big Brother

Also known as: A Love Story Starting at an Anime Convention

After transmigrating into a crossover anime world, I become Kyosuke Kosaka, the older brother of Kirino Kosaka.

In this 2D world where all kinds of romance anime have merged, I set out to help people.

Every time I help a beautiful girl, I can get a random reward and live the life of a winner.

But as the number of girls I help grows, things slowly start to feel a little off. They all start chasing after me and calling me big brother!

Oreimo: Big brother is mine! I decided that when we were kids.

My Dress-Up Darling: Big brother, I have a really daring cosplay outfit I want to show you in private.

The Quintessential Quintuplets: Guess which one of us spent last night with you?

Yukinoshita: If your little sister can call you big brother, so can I.

Light Music Club: Big brother, please train us even harder!
