I'm not sure specifically as 'hearm' might be a misspelling. If it's 'heart' light novel, it could be about various themes related to the heart such as love, courage, and emotional growth. But without more context, it's hard to say for sure.
Since I don't have access to this particular fanfic, it's difficult to say precisely. It could potentially be about the challenges and experiences Natsu might face while being pregnant in a world that combines the rules and settings of both the Natsu's original world and the DxD universe. Maybe it delves into how other characters react to this unexpected situation, or it could be more focused on the relationship aspects within this new scenario.
One popular sci - fi light novel is 'A Certain Magical Index'. It combines elements of science fiction with a unique magical system. Another is 'No Game No Life', which features a world ruled by games and has interesting sci - fi concepts. And 'Overlord' also has some sci - fi elements within its fantasy setting, especially with its in - game mechanics.
Begin by exploring different sub - genres within sci - fi light novels. For example, if you like time - travel or virtual reality concepts, look for novels that focus on those. You could also ask for recommendations on online forums or from friends who are into light novels. Once you've chosen a novel, take your time to understand the world - building and the characters at the start. Read a chapter or two at a time to really get into the story.
Sorry, as I don't really know what 'hearm light novel' is precisely, I can't recommend similar ones. But if it's a heart - themed light novel, you could try some popular ones like 'Your Lie in April' which has a lot of heart - touching moments about love, music and growth.
Well, you can try searching for it on dedicated fanfic platforms. First, check out AO3. They have a large collection of fanfics from various fandoms. If it's not there, then head to FanFiction.net. Another option could be Wattpad, although it has a more diverse range of content including original works. But remember, some fanfics might be hard to find if they are not properly tagged or if they are relatively new or from a less - known author.
Honestly, I don't have exact details on the new developments in Ysio manga. You might want to keep an eye on official manga channels or fan communities for the latest updates.
