RanSill

RanSill is the het ship between Rance and Sill Plain from the Rance Series fandom.

Canon
Before the events of the series begin, Rance buys Sill from a slave trader for 15,000 GOLD. While she originally had "Absolute Obedience Magic" put on her, it quickly wore off. But Sill stayed with Rance out of her own love for him. Sill considered Rance to be her hero because he saved her from such a horrible situation.

I/01
In Rance I and the remake 01, Sill serves Rance as his sidekick and slave. She will offer him help and heal him whenever Rance needs it. When Sill is captured by Lia, Rance rushes in to save her.

At one point Maris assumes that Rance and Sill are lovers. Various students passing by when Rance and Sill are in the park assume the same as well.

II/02
Sill follows Rance into the city of Custom in order to help him out. She gets lost in the dungeon that the Witches of Custom made, and is separated from Rance. There, she meets Bird Lithfie, another adventurer who got lost in the dungeon. Due to Sill's kind nature, Bird falls in love with her, and, upon hearing how Rance treats her, asks her to marry him and run away. However, Sill remains loyal to Rance. When Rance catches word of how Bird had been hitting on Sill, he told Bird to never try and take his woman ever again.

III/03
Towards the middle of the game, Sill is captured by the Dark Lord Satella. While Rance usually has a policy against harming women, he is willing to do so in order to save Sill from her. At one point, Sill is about to be raped by Helman soldiers, but Rance stops them before they can do so.

In the ending, Rance is about to be pulled into the eternal seal that the Demon King Gele is forcing him into. However, Sill rescues him in time, causing them to be teleported onto the floating city of Ylapu.

IV
After waking up in Ylapu, Sill befriends Freoncoise, a local manager at the bar. Sill works there for a bit of time, and Rance gets jealous that other men can see her in a waitress uniform.

At some point, Sill is captured by Toushin Upsilon. Rance becomes traumatized, fearing that she was dead, giving her a hug right after she was saved.

4.X
Due to his fear of losing her, Rance leaves Sill at their home. However, Sill still becomes very worried about Rance. So, she dresses up as Pink Mask (a parody of Sailor Moon) in order to keep watch over him. While Rance believes what Pink Mask says that she isn't actually Sill, she lied in order to make sure that he wouldn't have to worry.

Kichikuou
While Kichikuou is technically non-canon to the modern Rance timeline, the events presented in it are still worth mentioning.

Sill's status is one of the major factors to determine what ending you get in Kichikuou. The entire reason Rance becomes king of Leazas is because he wants to save Sill. When Rance gets married to Lia, even the other girls of his harem (?) such as Sel, Shizuka, and Maria question why he is marrying someone other than Sill.

If she is killed, Rance will find her body, and mourn her death. This is to the point where he orders his men to gangrape the woman who captured Sill in the first place, Ruberan, until she is dead. Rance will then later hold a funeral for Sill, putting his favorite shell on her grave, and crying, something he is only seen doing a couple times in the series. The infamous Demon King Ending can only be triggered if Sill is dead, implying that Rance has no reason to live when she is not by his side, causing him to seek revenge against the entire world. Him being attached to Satella is also possibly because she reminds him of Sill in a way as well.

In one of the endings, Sill can be frozen by the god Ludo. Ludo also says directly to Rance that Sill is what he values and cares about most in the world. The only way he is allowed to get her back is if he commits horrible actions and throws the world into chaos. He doesn't hesitate in choosing this path.

The True Ending of Kichikuou is of Rance leaving his position as king of Leazas, telling Sill himself that he only did it to get her back. The two then go on adventures together for the rest of their lives.

5D
In 5D, Rance and Sill begin searching through a mysterious cave together. They then stumble upon Genbu's Castle, being trapped in a pocket dimension. At one point, Rance leaves Sill inside Genbu's Castle, trying to get clues on how to get out. He considers leaving Sill there forever, as he made both Copandon Dott and Rizna Lanfbitt fall in love with him, but after seeing a vision of her in the stars, he remembered how "troublesome" things would be without her. So he goes back to get her.

After leaving Bird in Genbu's Castle, as it required at least one human at a time to be in there, Rance is forced to chose which girl he will stay with. When choosing between Rizna, Copa, Athena, and Sill, Rance tells Sill that this is her chance of being freed from slavery. However, Sill says that she wants to stay with Rance, and Rance picks her, saying that he would rather be with the girl who he knows best.

VI
At the start of Rance VI, Sill is separated from Rance, as Rance is, ironically, put into a slave camp for non-mages. After Rance escapes, he joins the resistance Ice Flame. Rance's first order for Ice Flame is for them to find Sill, who had gone missing. Once he finds her, while he is very tsun about it, Rance is genuinely happy, as he was very worried about Sill's safety.

Towards the end of the game, Sill has an odd dream. The duo visit the Calculator Cube where Sill obtains her ultimate weapon, revealing herself to be one of the girls fated to Rance.

In the final battle against the Dark Lord Kamilla, Rance and Sill are split from the rest of Ice Flame, and have to defeat her together.

Sengoku
In the beginning prologue of Sengoku, Sill suggests that their trip to JAPAN is like a honeymoon. Nobunaga also assumes that they're dating. In battle, Sill will help Rance out by healing his troops.

In the true route, Sill is frozen by the Demon King, Little Princess, as she jumped in the way to protect Rance. This is what leads to major development from Rance, as he begins to realize how much Sill means to him. He tries all the methods he can to save her. Most notably, he kisses her through the ice, hoping it will unfreeze her. While he isn't able to do so, he swears to himself that he will do all he can to save her, telling Kouhime in the ending that he'll check and see if the Kalar are able to help.

In the Isoroku route, Sill asks if Rance can have a child with her. He rejects this offer, but the player is still given her as one of the choices of the girls Rance can have children with.

Fanon
RanSill has had a rocky reception in the fandom, although with time it has gotten better.
