I love this manga and the feeling I get from the two of them(≧∀≦)
All of them available on this site by kaji eiri except Teikoku Kyoudai(which i havent read so i cant vouch for)
For example:
Keishichou Tokuhanka 007
Majo To Kiketsu No Kishi
Kainushi wa Akuma
These stories definately have a more youthful feel. But its still this vibe of like somehow passionate yet not lovers(early on in the stories at least). Or like a sense of unconscious reliance from one end and stability in the other...... maybe in words is too abstract(⌒▽⌒)
If you read them tell me what you think! This is my favorite author
Damn it
