There are a few reasons why you might not see posts on this friends page:

• Hoshi no Senshi: Soldiers of the Stars might have no friends defined. If you are Hoshi no Senshi: Soldiers of the Stars, you can edit your InsaneJournal friends so they show up here.
• Hoshi no Senshi: Soldiers of the Stars might have friends defined, but all of their friend's posts might be over two weeks old (according to the times on our servers), and thus wouldn't be displayed here.
• Hoshi no Senshi: Soldiers of the Stars might have friends defined that post only protected entries that you can't view, because they haven't defined you as a friend in return.
