I have to say that Kiro losing her virginity was not one I saw coming. I'm expecting more of her brash nature and "let's tear it up!" and what do we get? A very tender moment when she basically admits she's falling for Steele. I say that because she starts to go through all the reasons why she's saving her virginity and who for and just fades into "That's you, isn't it?" The sheer emotional weight of the epiphany really sets the stage for the scene being as much about them becoming closer as it is about Kiro basically getting fucked senseless.
Not to mention she teases us with the idea of joining us on the ship and having a few pups. I like the hope this offers late in the game but I can easily see it just being dirty talk to tickle Steele's more primal side.
Jim's characters really hit the "awesome Waifu" index and it's hard to pick one out of all of them.
Another character that while already discussed in a different thread deserves mentioning in my list here. Syri. I love Anno really I do, but I cannot shake the "fuckbuddies and friends" vibe from her. There are only 2 things I've seen that Anno changed by moving to the ship, well 3: She changed her address, both business and personal, she is now boinking Steele, and arguably gets to see Kaede a lot more or at least in different places. Beyond that, her lifestyle, relationships, and goals haven't really changed.
Syri on the other hand, again, starts out like Kiro and has the "wild and raunchy sex and hanging out" start to the relationship...but then she hits you with scenes like coming to your ship because she missed you that much as well as giving you her panties. Then there's the puppyslutmas where she basically will go, if you ask her, and make peace with her family after years of not contacting them, and putting on a dress if Steele requests it. Considering how independent she is and how strong her sense of self is, to the point where she adapted and even enjoys the "accident". Syri is basically letting Steele choose her appearance, and by association with the chosen article of clothing, her gender identity as well. If that isn't a sign of trust and faith I don't know what is.
Penny is another one that seems one-note until she hits you with the emotional connection. She's happy where she is in life and while not joining Steele on his adventures, that actually adds impact to her mentioning having a cute mate in her list of reasons why she's happy. She's one that I could see having kits eventually as a natural progression of her relationship with Steele, once she felt like she had reached the point where she wanted to. If that happened, she'd raise the kid herself but make sure to include Steele in the kit's life. Again, this is just me reading into the character but she offers hot and wild fun and bits of "daw" as well.
On the less "waifu" side, I love teasing Kelly and making as if to walk away. The look I imagine on her face when called on her bluff is hilarious.
I like when Reaha goes a little patch happy and thinks she can handle Steele...only to be proven very, and delightfully wrong.
I love messing with Renvra and leaving her well packed with fertilised eggs, the "turnabout is fair play" makes me smirk as she gets a taste of being overfull on eggs.
Inviting Saendra with Kiro is always a good time, the gorgeous kitty-bitch of a redhead never able to resist her eyes being bigger than her stomach.
Gianna's "oops" when she and Steel break the bed is another moment of pure amusement for me.
