For now I'll stick with scoring my possible candidates. If you're interested after the score, I'll give you a bigger rundown. (This way I don't have to give a ridiculously comprehensive profile on anyone you already know)
Keep in mind I'm just tossing out random possibilities - many of these were mental exercises in 'ye gods, how badly can I hurt my brain concieving of these fiancees'.
Nodoka Miyazaki (Negima)
Female: Yes
Tomboy: No way
Canon: Yep
Strong-willed: ... I don't see her as pushing her suit
Engagement: Easy
Noncombatant: Yeah. She's combat-support at best
Delusions of Normality: 'fraid not
Score: 17
Setsuna Sakurazaki (Negima)
Female: Yes
Tomboy: Not in the 'shameless' sense, but I'd say so
Canon: Easy.
Strong-willed:
Hell yeah.
Engagement: Well, it'd be interesting to squeeze it around Motoko's, but it could be worked out
Noncombatant: Nope.
Delusions of Normality: Uh-uh.
Score: 25
Evangeline AK MacDowell (Negima)
Female: Yes
Tomboy: Not especially
Canon: Doable
Strong-willed:
Hell yes!
Engagement: It twists my fragile mind, but it can be done
Noncombatant: The girl utterly annihilated a demon-god and found it fun
Delusions of Normality: ... Vampire.
Score: 19
Kasumi Asakura (Negima)
Female: Yes
Tomboy: Rather brash personality
Canon: Same as ever
Strong-willed: I'd say so
Engagement: Potentially doable
Noncombatant: Definitely. She's a spy by talent, not a fighter
Delusions of Normality: Not really
Score: 27
Riku Harada (DN Angel)
Female: Yes
Tomboy:
DefinitelyCanon: Should be easy enough
Strong-willed: Absolutely
Engagement: Probably doable
Noncombatant: Combat skills equal zero
Delusions of Normality: Not delusional, unfortunately. Perfect candidate otherwise, eh?
Score: 27
Ayane Isuzu (Gatekeepers 21)
Female: Yes
Tomboy: ... Hard to tell. Not in a literal sense, but the attitude you seem to be looking for is there.
Canon: Should be doable, I guess
Strong-willed: Yes, yes, yes
Engagement: Can be done
Noncombatant: She's one of the toughest in her environment
Delusions of Normality: ... She's a mercenary supernatural-hunter.
Score: 25
Now for the
really twisted ones! All from Kara no Kyokai. Before being tempted, please note that Azaka's the only one here who can evade the 'psychopathic' designation.
Shiki Ryogi
Female: Yes
Tomboy: She talks like a guy, literally. I'd say so.
Canon: Doable
Strong-willed: To the point of obsession. Although the 'interest' factor may be harder
Engagement: Daughter of what's been described as 'an old family', and the heir
Noncombatant: ... We're talking a girl who has been described as being able to kill God, if he lived
Delusions of Normality: Split-personality disorder, converses with a mage, seems to end up running into and killing every supernatural threat in her area...
Score: Restricting points due to disinterest - 21; Giving points for stubborn - 25
Kirie Fujyou
Female: Yes
Tomboy: Not in the slightest
Canon: Yep
Strong-willed: Not so much. Although I
really don't see her being willing to let go of a frequent visitor. I'd give points, I think...
Engagement: Another old family
Noncombatant: She can probably kill the NWC in a night if it proved necessary, even though she can't move from her hospital bed. Although other than straight-out killing, her 'combat' abilities are support at best.
Delusions of Normality: Nope
Score: 19. 21 if you count in the fact that she's not much good at combat
Fujino Asagami
Female: Yes
Tomboy: Hell no
Canon: Yep
Strong-willed: ... Not really.
Engagement: Easy enough
Noncombatant: The girl can outperform Shiki in terms of raw power, and only lost due to lack of actual battle ability
Delusions of Normality: Strongest psychic on record? Check.
Score: 15
Azaka Kokuto
Female: Yes
Tomboy: Has been described as such
Canon: Could be done
Strong-willed:
Very much so. Although she's a little too fixated on her brother to push the engagement
Engagement: Scenario already forming, gods save me
Noncombatant: Not entirely, although she
is the weakest combatant in her story
Delusions of Normality: Trainee sorceress
Score: Giving points for stubborn - 27; Restricting points for disinterest - 23

You clearly know nothing of the game or extended universe
The anime pussified everybody. Read the manga if you want something available in English that shows it as it was meant to be. Ciel lost all her agility and you never get to see her fricken
huge pile-driver/gun thing, Shiki lost his asskicking 'mood', Nero lost almost everything interesting (he was described as being tougher to destroy than a fricken
continent!), Akiha was actually tough enough to threaten the much more powerful Shiki of the game (and utterly pwn Roa), Roa himself even got 'trimmed'... And Arcueid lost a great deal of her physical prowess, not to mention her particularly interesting ability - Imagination Realization, aka 'Marble Phantasm', which allows her to basically manifest
anything that can exist in nature: blades of air, a black hole, chains (as seen in the fighting game), a fricken horde of tigers, a bomb in place of someone's precious organs... The limits of her power are only the limits of her creativity. That's completely ignoring her regen - she's a concentration of natural energy, and managed to physically recover
overnight from getting chopped into 17 seperate pieces by an ability that can potentially kill God - and you
saw that. Keep in mind, too, that most of this is when she's
massively limited, ie recovering from being killed by Shiki's 'gift'
and still directing most of her powers inward to suppress her craving for blood. And she recovered from a similar 'death'
again (that's how she came back at the end of the anime), although that
finally pushed her power level low enough that she couldn't supress her bloodlust.
Imagine, for a minute, what she could do if she cut loose. You may now wet yourself

Now wet yourself again: her big sister's tougher. And Arc's the potential reincarnation for the template of the True Ancestors, Crimson Moon.
Type-Moon characters have been described by their
fans as 'munchkins'.
There is no problem that cannot be solved through the proper application of immense levels of firepower.
