Before I head off for, I wanted to share the link to OUTDOOR a free online "EcoMIC" by Yuichi Yokoyama. This three-chapter story is hosted at MouRa's Ecologue site. MouRa is "a digital publishing platform which covers the whole Kodansha universe".
You can check out all 3 chapters over on their site!
Thanks to Kevin at Laser Crab Revue for sending this link!
Oh, and if you're still not satiated with online manga reading (for free!), the SigIKKI site is still posting tons of new chapters... including their newest series Bob and His Funky Crew.
