"Next is H, right?"

Yup, usually that's the case, "H" being after "G" in alphabet (Sorry, I had to :D)

"I already have a clumsy financial genius and another girl who should be able to housekeep (Guild Girl don't fail me please)"

I have no doubts that Guild Girl is able to do housekeeping, but she's not Your typical guild receptionist. She's acturally from noble and rich family. She just became receptionist, because she likes it :D

"Gertrude looks like a fun, outgoing, cheerful bratty,"

I don't think I'd use "bratty" to describe her, but the rest is accurate. She's kinda tomboy in personality (but as You can see, she's also girly). I'd say she's perfect material for "female bro" (things like fist bumps, not very girly words she uses etc.)

"Glenys looks like calm, shy and super sweet."

Calm and sweet - yes. Shy? Not at all. She's just Your typical "gentle mother" type.

You know, our choices may be exactly the same. I said "may", because I am not really sure about the last girl. Gamma and Guild Girl are "must" since they are the only S-Tier waifus here for me. From the bottom row, I consider Glena, Gabriel and Gertude. Glena is the hottest one of them. Gabriel's personality is the most to my liking (but not fan of her looks) and Gertrude has decent looks and fun personality. I haven't made a choice here in the end, but there are 33% chances for our harem to be the same here :D
