I would go with "-dono"

"-dono" means souvereign or princess. That is literally the exact opposite of her social status, haha.

I know but actually my point it was going with the most honorific possible XD

Phase-Chan!

Phase-Chan sounds adorable.

The funnny thing would be to use her full name: "Kasumi α Phase 4-chan" or "Kasumi α Phase 4 Prototype-chan" XD

=) Yes.

I think either one will do. 'Chan' is used as an honorific title for younger girls, 'San' is polite in a more general sense and 'Sama' is mostly used for people with higher status than you. Phase-chan is very cute though!! :3

What's the japanese term for "it" or "thing"? "koto"? Would be also an idea, since she's actually not even human.

One does refer to her with "she" or "her", but can you label something made out of smoke or jelly (like Alpha and the other Kasumi clone) as female?

Hm ... philosophical^^

Well... she has a human body so one could debate whether she is human or not. I consider her human.

I don't think you address a weapon with a formal title.

Where's @Chapstick?^^

Personally, I would also consider her as human

Yeah, but the only people who know of her existence regard her as a weapon.

"Dear weapon, please go an beat up Bayman" - Donovan.

Well of course she is an human and a female, these elements have nothing to do with the way how she was created (on the opposite they are debatable for Alpha 152 taking in regard her singular nature).

I really hope that she will get some true love in the future of the story, I would like to see Kasumi consider her as a sister (after that Phase 4 will eventually change side).

Actually, the gender doesn't seem to be debatable for Alpha too because she has breasts and get's a schoolgirl outfit in LR.

Species is, because I can also let my cat or dog wear a skirt (Some people really do I heared). Although one shouldn't jump to conclusions from clothing.

Well, actually the gender is something related to the sex of the subject: if Alpha-152 has really no reproductive organs/apparate (how her model in game seems to suggest), then it should be considered technically an "it" despite any other things (female breasts or outfits).

If something Alpha-152's gender is IMO debatable because previously she was a female (human too), according to the new canon that see her being a mutation of the original Kasumi Alpha.

Kasumi-san. I'm sure she would tell them that's her name. And I'm sure if people knew she was some science project, they'd just refer to her as Phase-4 (prolly not to her face, thought).
