Waifu

Ishtar is always my #1! I mean, it’s also Rin for cryin our loud lol!

Summer Scathach is just to obvious so my personal follow ups are rider Mordred and Tama lancer. I saved up over 500 SQs for those summer banners haha!

Eresh because why not?
Special mention to Musashi also..

Illya- I mean Fran.

i mean, you're pretty much asking who our favorite waifu is and ranking them. which isn't a very nice thing to do to our waifus, but sure, i'll do it.

#1 baber alter in all her forms (og, lancer, santa, maid)
#2 shishou in all her forms (tights, summer, skadi)
#3 rin aka ishtar & eresh
#4 foxy-chan in all her forms (kimono, summer, maid)
#5 the holy maiden and her altered form (not into lolis so i'm excluding jailter)

well that's my top 5 and the order i'll grail. i have baber alter og maxed, latler at 92 where i'll stop, gonna grail maid to 100, and i'll grail santa to 92 as well. once that happens, and if i manage to grab the rest of the shishous, they're gonna get grailed once i get those grails. but i digress.

Shishou\jeanne d arc and musashi are my top 3 followed by nero and larturia.
I like asagami fujino too

As Waifus I consider those, where I like their character, their background, their design, pretty much everything the most.
So in terms of Waifu, mine would be:
- Kiyohime
- Helena
- Arturia
- Shiki

But being my waifus doesn't mean I consider them the sexiest ones. I think the sexy Servants need to have a revealing design or something that accentuates their body, which would be in my case:
- Arturia (Lancer Alter)
- Scathach (both) (not Skadi imo)
- Nitocris
- Chloe (that final Ascension)
- Sanzang
- the upcoming Fuyajo Caster and Midrash Caster
- Shuten-Douji
(pretty much every summer version of a Servant...)
- Altera (yeah, I think she's really sexy!)
I mean, I'll be honest: I'm a simple mind. If a Servant shows a lot of skin, I find it sexy.

That's it from me

Edit: i knew it! I forgot someone and feel bad now.
Ishtar - she's the only one, that falls in both categories: Waifu and sexy.
She's a strong candidate for Level 100.

Well, as for me it goes:
1) Kiyohime (both versions) - yandere for life! Also, housewife material here. Also berserker very good for farming and lancer for boss killing: her NP killed archer Demon Pillar for me.
2) Tamamo-no-Mae (caster and lancer versions) - again, housewife material. Also big boobs. Also very good gameplay-vise.
3) Parvaty - Sakura-face NUFF SAID. Aaand again, housewife material. Yep, I'm pretty lonely *crying in the corner*
4) Scathach (all versions) - very hot: those melons! And in lore she also very thirsty. Also, good gameplay-vise.
5) Jeanne D'Arc (ruler version) - very kind and very hot body. Again, boobs are ruling!

Those are pretty notable for me.

My favorites in no particular order are Nero, Quetzalcoatl, Mordred, Jeanne Alter, Francis Drake, and Penthesilea. I definitely have a type.

All Sakura faces except Passionlip. I just don't like her character design (her chest is too much for me). That's why I gonna skips her & BB summer version.

For me Medea will always be #1. But trailing just behind Medea I’d go with Medusa, Raikou, Shishou, Fran and of course Mashu. Well they’d be my picks anyway.

Salter, Jeanne family, Nero, and Elizabeth are my top waifu and I plan to get every form of elichan (I don't have her original form).

In case of sexiest, Meltlilith is on top of ranking (from her cloth).

However, number of waifu is always increase in every second we live. My waifu surely increase in future.

Marie Antoinette

She's fucking cute.

Judging by the final ascension art, it should be Nitocris and Summer Scathach hands down.

Uhhh Kiyohime... that’s pretty much about it. Maybe scathach and Jeanne

Sanzang will always be my #1 waifu. I love my big titty monk who's dumb on main. I was incredibly happy when I got her as my GSSR.

My 2nd waifu is Martha, both Rider and Ruler. Martha as a whole.

Tied in 3rd place are both Mordred and Shiki. If only I had any form of Shiki... guess I should wait until next year for the KNK re-run.

To name the first three that came to mind: Mash, both Ishtar and Ereshkigal, and Nitocris. There are many other good waifus, but those were the first I thought of.
