I really like 'Sanegiyuu: The Unspoken Understanding'. It delves deep into the unspoken connection between Sanemi and Giyuu. The author does an amazing job of portraying their internal struggles and how they gradually come to understand each other better. There are some really touching moments in this fanfic that make it a must - read for sanegiyuu fans.

The main character is Sanemi. Depending on the type of light novel, there could be a group of characters around him. For instance, if it's an adventure - themed one, there might be fellow adventurers who each have their own skills and personalities.

And then there might be a mysterious character whose true intentions are not clear at first, but as the story unfolds, they turn out to be either a great ally or a formidable foe.
