See, this is why I'm more interested by the lore than anything else. All we know about Akaren is that :
-She's a barmaid of some sort during the day with a happy attitude but a straightfaced professional at night.
-She's good enough at the ninja stuff that her superior gives her the mission to take off the rapist bandit gang.
-She seems to enjoy the sex enough that she closes her eyes when riding the boomerang enemies, lolls out her tongue when riding the big guys and actively uses puppet strings on the boss so that he fucking full nelsons her in the unreleased animation, indicating that she'd enjoy bottoming in a less serious context.
-Despite this, she's straight-faced when selecting scrolls and using them.
-She never, ever shows any kind of embarassment at any of this, so it's normal enough to her.
She could just cowgirl all of her opponents to get a quick mana refill or increase her power or however it works but she goes out of her way to enjoy herself.
Also, it seems that she can only refill her mana chakra cum thing through vaginal sex. Maybe her womb is the key to her mystical abilities like in some Fan No Hitori story -- except instead of needing to remain pure, it has to be filled all the time.
Are there any ninjas ? Was she brought up as a giga slut or recruited later ? Why does she need a day job ? Why do her scrolls need to be buttplugged but her energy vaginally harvested ? I want more of this.
And Yuri. I want a lot of Yuri.
