Another place to look is FanFiction.net. There are a lot of fan - created stories on this platform. However, the quality can vary. You'll need to search specifically for 'yuki x yuno' and then go through the results to find the ones that interest you. Some of the fanfics might be hidden in different categories, so you may need to be a bit patient when searching.
You can start by looking on large fanfiction platforms like Archive of Our Own. Just type in 'yuki x yuno' and then look for any stories that might involve pregnancy in the summary or tags.
Some niche anime - related forums might also have user - shared yuki x yuno fanfiction. These forums are often a great place to discover unique and less - known stories that might not be as easily found on the bigger platforms.
The 'Suicidal Yuki x Yuno Fanfic' could potentially be a very dark and emotional piece. If Yuki is suicidal, it might be due to some backstory like a tragic past or feeling of hopelessness. Yuno's role could be crucial in either aggravating the situation or being the one ray of hope for Yuki. Maybe it's set in a world where their relationship is strained by Yuki's mental state and Yuno's attempts to deal with it.
Fanfiction.net is also a great place. There are numerous fanfictions related to different pairings in Mirai Nikki. Just use the search bar and look for Yuki and Yuno pairings. However, the quality may vary, so you might need to read a few to find the really good ones.
You could try looking on dedicated anime or manga fanfiction platforms. Some of these platforms allow for different ratings, and you may be able to find 'yuno and yuki' fanfictions rated M there. But be cautious as not all platforms are well - regulated, and you might come across some inappropriate content. Fanfiction.net is also a possibility, but again, it's important to use the search and filtering options correctly.
There's this 'yuki x yuno fanfic' called 'Under the Stars'. In it, Yuki and Yuno meet under a starlit sky and from there, their story unfolds. It's a sweet and gentle story that shows their growing affection for one another. There are also fanfics that are part of a series, like 'The Yuki - Yuno Chronicles' which spans multiple installments and really dives into different aspects of their relationship.
One possible theme could be mental health. Yuki's suicidal state clearly points to this. Another theme might be redemption, if Yuno is trying to save Yuki from that state. Also, the theme of love in the face of darkness could be present, as their relationship is central.
I'm sorry, but I can't really recommend "lemon" fanfics as they often involve inappropriate or adult - themed content. However, you can try searching on fanfic - dedicated websites like Archive of Our Own and filter for non - explicit stories about Yuki and Yuno.
I'm not sure specifically if there is a 'yuki x yuno pregnant fanfiction' out there. Fanfiction can cover a vast range of themes and pairings, but it depends on the popularity of the characters 'yuki' and 'yuno' within the fanfiction community for such a specific plot to exist. You could try searching on popular fanfiction websites.
One characteristic is the exploration of their unique bond. Whether it's a friendship or something more, the fanfiction often dives into how Yuno and Yuki interact with each other. Another is the use of their distinct personalities. Yuno might be more assertive while Yuki is more gentle, and this contrast is often highlighted.
