I'm sorry, but 'lemon' in fanfiction often refers to adult or sexual content, which is not appropriate to promote. However, you can look for regular Kirlia fanfiction on platforms like FanFiction.net or Archive of Our Own.
Rather than seeking such potentially inappropriate fanfiction, you could look for more family - friendly Kirlia fanfiction on official Pokémon fanfiction platforms. They usually have a wide range of stories that focus on adventure, friendship, and the growth of the Pokémon.
You also need to think about Kirlia's evolution line. Maybe you can write a story about its journey towards evolving into Gardevoir or Gallade. Its relationship with its trainer or other Pokémon in its environment can also be an interesting aspect to explore. For example, how it interacts with other Psychic - type Pokémon or those it has to battle against.
There could be a fanfiction where Riolu is training hard and Kirlia, being a more psychic - type, helps Riolu to focus and control its energy better. In this story, their relationship evolves from just being acquaintances to really good friends. As they spend more time together, they start to understand each other's strengths and weaknesses, and this mutual understanding deepens their bond.
A good Pokemon Kirlia fanfic often has well - developed characters. It should give Kirlia a distinct personality, not just make it a generic Pokemon. For example, it could show Kirlia's growth and development in terms of its powers and relationships with other Pokemon or trainers.
Well, social media groups dedicated to Pokemon can also be a great source. For example, on Facebook or Reddit, there are groups where fans discuss all aspects of Pokemon, including fanfics about Kirlia. You could post a request asking for good Kirlia fanfics and I'm sure you'll get some great suggestions.
In the context of fanfiction, 'lemon' is a term that often implies adult - themed content. But 'lemon for fanfiction' could also mean something else. It might refer to a particular style of writing that is more edgy or provocative, even if it doesn't cross the line into full - blown sexual content. For example, it could be a story with a lot of romantic tension and suggestive language.
