You can download the replica manga font for free from Celsys if you have a license for the Japanese version of CSP or CSPEX. First goto the website and goto the downloads tab. Then scroll down and click on the button that says [特典 追加素材のダウンロード].
Input your license number into the text field.
You can now download the generic replica of the manga font (the real one costs hundreds of dosh). Also underneath are .zip files containing a database of screentones from 3 major screentone companies. This is very expensive stuff and can be installed as materials in CSP:EX Japanese version ONLY. The font can be installed normally.
