Let's take Archer. He could be forced to confront his past self in a new way because of the mix of mana and od. Suppose there's a situation where his mana is corrupted by od, and he has to find a way to purify it. This process could make him re - evaluate his actions and decisions in his previous lives, thus deepening his character development. He might become more empathetic or more determined to break free from his pre - determined fate.
For a character like Rin, her understanding and use of mana could be enhanced by the introduction of od. Maybe she starts to question her traditional magical training when she discovers the power of this combination. This could lead to her developing new spells or techniques, and also a more open - minded view of magic in general.
One possible interesting plot could be a character who has the power of mana suddenly gaining the ability related to od. For example, Shirou could discover that his mana can be combined with od in a unique way that gives him new abilities to face the challenges in the Holy Grail War. This could change the power dynamics and his relationships with other characters like Saber.
In the Fate Stay Night visual novel, mana transfer is a crucial concept. It is mainly related to the relationship between Masters and Servants. Masters provide mana to Servants, which is like the energy source for Servants to exist and perform their powerful abilities in the Holy Grail War. Without sufficient mana transfer, a Servant may not be able to function at their best or may even disappear.
The visualization of mana transfer in the Fate Stay Night visual novel is quite interesting. It can be seen in the form of auras or energy streams. When a Master sends mana to a Servant, the visual novel may show a soft light or a series of lines connecting them, indicating the flow of mana. Also, the expressions on the characters' faces, like the Master looking a bit tired and the Servant looking more vibrant, can be part of this visualization.
You should also think about their personality traits. Maybe they are a bit of a loner because they spent so much time gaming alone, but they gradually open up as they interact with the Fate characters. Their appearance can also be related to gaming. They could wear a piece of gaming merchandise as a sort of lucky charm that has some special significance in the story. Additionally, give them goals that are both related to their gamer side and the Fate Stay Night world. For instance, they might want to collect all the different Servant cards like in a collectible card game.
In this part, the character development is more in - depth. For example, Shirou's development from a somewhat naive idealist to a more complex character is more pronounced. He faces harsher realities and has to reevaluate his beliefs more than in the previous parts.
The 'System Gamer' aspect changes the story by adding a new layer of progression. In the original, characters develop through their experiences and training in a more traditional way. But in the fanfiction, with the system gamer element, they can level up, gain new skills instantly, and have stats like in a game. For example, a character might be able to see their 'strength' or 'intelligence' stats and work on improving them.
Gluttony can be incorporated by making it a flaw that she has to overcome. For example, she might start off being too focused on satisfying her appetite, which causes her to make mistakes in her Assassin duties. As she progresses in her story, she could learn self - control and discipline, which are important traits for an Assassin. This change would show her growth as a character.
It could be a new character who has been brought into the Fate Stay Night world with gamer - like abilities. This character might be from our world and has to use their gaming knowledge to survive and thrive in this new and dangerous environment.
Ilya is portrayed as a complex character. She has an innocent look but a deep and sometimes dark side. Her actions can be unpredictable, like when she shows her determination in the Grail War.
