Grandfather said that our family has an ancestral treasure that everyone wants to get.
So I got rid of all the people who tried to snatch the treasure.
A heroine with a mysterious background who relied on talking in the early stage and artillery in the later stage.
In addition to fighting pirates, he also has sex with someone who is also a pirate - maybe the male protagonist.
The heroine's cute best friend suddenly became aware of her talent and started cheating.
Someone who has a very hard life but also has a mysterious background... An ally, I guess.
The purpose of the military-bandit-business triangle group - just do it if you don't accept life or death!
Ps: I would have forgotten the names of the protagonists if I hadn't seen the series of copywriting.
