Easter had another Knight Case Files character's birthday. This time, we celebrate the enigmatic Abend, whose impact to the world can be felt long after he departs it.

Kingdom Calendar Year 575, on a sunny day, Wilhelm receives a (very) belated birthday cake and has a cheerful conversation with his friends, Topherf and Leon. Happy birthday, Wilhelm! And thank you to utino877 on Twitter for the beautiful illustration.

This is Topherf, a gender-bending alchemist who changes her appearance as easily as changing an outfit. She's stylish and lively, and already very fond of Wilhelm. She thinks they've met before, but Wilhelm surely would've remembered meeting someone like her.

Let's introduce the lead character of Knight Case Files, Wilhelm! He's a brand new member of the Royal Guard, still trying to find his place with them. He's also got some secrets of his own...👀

Thanks to you, Knight Case Files has achieved over 777 wishlists on Steam! You may recognise these gentlemen if you've played the demo: the grandfather Abend in white, and his grandson Schatten in black. And if not, you can try the demo here: store.steampowered.com/app/2656440/...

We're thrilled to reveal that we'll be bringing Knight Case Files, a gorgeous dark fantasy visual novel by HyoukanStudio, to English players! A demo is available now, so you can fall into a world of knights, necromancy, and a gender-bending alchemist. store.steampowered.com/app/2656440/...
