Oh, we went full typical isekai fantasy.
First person you saved can be one of multiple people. A slave, elf, loli, human or beastgirl. A princess or nobility of some sort. A merchant. If a merchant or nobility or royalty, open the avenue for immediate sponsorship. If a merchant, one of two options, a skilled but struggling merchant done wrong by another force or who is solely missing something that the MC will provide to make them immensely successful or they were already successful and yet somehow even with the elite guards they hired failed to be protected and now dotes on the MC who will either make it a quid pro quo, a pro bono, or will add the merchant herself, or if the merchant is male, the merchant's daughter into his harem.
And now with this we reinforce that the MC is not a trapper, he's not some Techmo's Deception trap master. He's just a typical magical swordsman who will use a quirky combination of arrows and traps to emulate big magic spells, but ultimately not be a trap master. And instead of buff magic, it's just arrow magic to make him move super duper fast and attack super duper hard.
And of course now we establish the previous party wanted to harem him, so now we open up the route for them to get NTR'd by a new harem, or they will be his harem once he shows how much more alpha powerful he is now that he is a magical swordsman (master trapper allegedly).
I am mildly peeved that we don't get to see actual traps and strategy, and instead just straightforward magic swordsman bull. I knew this was going to be trash junk food, but I at least wanted some variation in the flavor.
