I recommend watching the original Japanese dubbed version with English subtitles. At that time translation was rough in most anime but this has since then improved.
(For German readers I recommend the German sub, the used the same people who dubbed the Stargate series which did a really good job in both cases.)
Keepass2 is also Open-Source and .Net because as far as I know .Net offers some extra security on Windows like locking the desktop while entering the master password.
No need for a CoC.
