The main characters are Cabba and Kale, of course. Cabba is a Saiyan from Universe 6 known for his strong sense of justice and combat skills. Kale is also from Universe 6, a female Saiyan with a shy and timid nature at first, but with great hidden power.
I don't recall any light novels that specifically focus on Kale Ale. Most light novels tend to revolve around common themes like adventure, romance, or fantasy elements rather than a particular beverage like Kale Ale.
One idea could be a story where Cabba helps Caulifla and Kale train for a big tournament. They face various challenges together and Cabba's unique fighting style influences the sisters to develop new techniques. In the end, they all become stronger and their friendship deepens.
One popular Broly and Kale fanfic is 'The Saiyan Bond' which explores their relationship in a unique way. It shows how they might train together and overcome challenges side by side.
As a fan of online literature, I can't give subjective opinions because everyone's preferences and tastes are different. However, He Kale was a well-known online author. Her works had a unique style and plot twists that were deeply loved by readers. If you are looking for a good novel, I suggest you first understand your interests and hobbies, then read some novels that you are interested in and see which novels suit your taste. You can also go to He Kale's official website or social media to learn about her latest works so that you can better understand her novels.
In a fanfic, it could be that Cabba and Kale are both on a quest to find a rare and powerful energy source. They cross paths and initially are distrustful. However, as they search for clues and overcome obstacles like dangerous terrains and traps, they realize they are better off as allies. Along the way, they also share stories about their respective families and cultures, forging a bond that goes beyond just their power - related goals.
A plotline could involve Broly being sent to Kale's universe by some sort of interdimensional rift. Kale initially sees him as a threat and attacks. But as the fight progresses, they start to understand each other's power and motives. Or perhaps a fanfic could have a story where both Broly and Kale are training on the same planet. Their training methods clash, leading to a fight where they both learn from each other and grow stronger in the process.
As I don't know what 'va pu kale short stories' are, it's hard to say. But generally, short stories often have concise plots, vivid characters in a limited space, and can convey deep themes quickly.
