As per Eromaniac's request, I've re-uploaded the package for him. I'm putting the Bigfile link publicly here, good for 30 days from last download only as it isn't my preferred filehost.
Just a heads up, you might want to prepare to update this soon. It suffers from no-progress bug that is currently under rapid debugging. Scheduled to be fixed on May 1st at 22:00 JST.
It's out, update please. 聖騎士リアナ to v3.5
