Kodansha Comics has been around for less than a decade, but in that time it has managed to put out some remarkable titles. Now, in the latest Humble Comics Bundle, you can get a bunch of those good books for under $20 to benefit the CBLDF, Worldreader and the Mental Health Foundation.

The marquee title here is Attack On Titan --- one volume unlocks with each tier. The first tier can cost you absolutely nothing, and besides Titan volume 1, you also get the first volume of horror manga Parasyte and the drama Space Brothers.

By spending more money, you also get acclaimed series like the supernatural mystery Ajin: Demi-Human, the fun fantasy The Seven Deadly Sins and, at the very top, a brand new omnibus of Yukito Koshiro's Battle Angel Alita: Last Order (a sequel to the original Battle Angel Alita).

But if you're committed to spending no or as little money as possible, I'd get the bottom tier for the first volume of Vinland Saga. A sweeping historical epic by Makoto Yukimura, it tells the actual story of historical Viking explorer Thorfinn, inspired by Leif Ericsson to journey to the West and a land Ericsson called "Vinland." With a gripping story and meticulous, incredible artwork, it's a favorite of comics creators the world over, including Faith Erin Hicks, who drew a series of 4-koma, or 4-panel gag comics, for the most recent Kodansha volume).

If you want to see what all the buzz is about, and get some other great comics in the bargain, take some time in the next 12 days and donate as much or as little as you like!
