Also where exactly is the Void Gate and smurf is Sage all good to go, beyond mechanics?
I have no idea how his mechanics would work, since he isn't really doing any magic, technically, when he calls for help...I suppose one could see his mana costs as outstaying his welcome or something, but that would be better called favor and probably be different for esch element and using multiple in conjunction could affect the cost(they don't all get along, but some, like Wind and Water, are friends) and youncouldn't exactly drain him of it like you can mana and...bleh. Stupid mechanics system not fitting every situation incredibly precisely exactly how
I want it to
HK-47 doesn't count, since he's HK-47 and would never deign to make tiny robotic babies with any android that considers meatbags worthy of consideration.
Maid-chan can be considered creepy. Using japanese suffixes when you aren't japanese, aren't speaking to someone who is japaneseand and quite traditional about it, and haven't lived in Japan for significant portions of your life, is kinda weird and/or possibly vaguely racist depending on how you look at it(I don't really see it as racist, but it plays into the whole fetishization of Japan that occurs and it's weird and mildly disturbing to me, but my mom also majored in Japanese and went there for an exchange program so I'm not exactly one to talk). The maid bit is weird only in conjunction with it, because of the connotations japanese anime gives maids, though if that's her actual job and she's fine with it, it might not be all that much.
Basically, I can see how it could be creepy, but it's not all that creepy compared to building a replica of someone without their knowledge(without permission is rude, but without knowledge is creepy). He's also actively trying to create a harem, or at least his player is, which isn't quite creepy, per se, but is disturbing on a different level, especially given he's a hyperfertility totem or whatever.
If he impregnates Kaotaro, you're all fucked, by the way. SERT ain't got nothin' on robotic doom-harbinger babies. So, uh...don't do that. Please. That would throw the plot so far off the rails the only way to get back on would be to hit it hard enough mid-flight that it continues around the world and lands back on them.
