I have been looking Ore Wa (Orewa?) Teppei by Tetsuya Chiba and Shin Tekken Chinmi. Ore wa teppei (I am Teppei) was released in the 70s so I dont know if scanlations even exists. It's about a kid who always gets himself in trouble and lives in the woods. He then goes to fight in some high school kendo championship and by the end of the book he goes back to the woods again. As for Shn tekken chinmi I found some group that scanlated an early portion but found no links for the file.

Thanks to anyone who can help .
