alchemichael I’m not sure if my answer went through or not because tumblr is bad, so I’ll post the information here as well. You asked me about the English version of Matsumoto Taiyou’s No. 5. There are some volumes published by Viz that are now probably out of print. The series was dropped after the second volume b/c of very poor sales in the states. I think it was published before Viz established the English side of its Signature Ikki line of series that were serialized in Ikki magazine and didn’t get a second chance after it formed.
As far as the English version goes, you can read scanlations of the series (should be on bato.to or whatever other aggregate site) that were completed and there’s also an official translation available through the "No. 5 Taiyo Matsumoto [IKKI COMiX] application" which you can view on any IOS device. The application includes some animated videos with it too, I think. I remember that the typesetting of the digital version from the application isn’t all that great though.
It’s a fun series, a pretty interesting take on the super hero team trope.
