Aiko

Aiko is a Yuki-Onna serving as the boss for the Will Side of the Will-Power Temple, making use of her power over the cold to tempt you into warming up within her incredibly comfy kimono. She is a close - and intimate - friend of Bed-Chan and the two spend most of their time hanging out with one another. She is looking for a husband and is also bisexual, despite her poor attempts at hiding it.

In-Game Description
"A plush woman with long light blue hair that has delicate bangs framing her face, snow white skin, and deep blue piercing eyes. Her lips are plump, coated in an icy blue lipstick, and every time she exhales, a small cloud of condensation forms in front of them, leaving them slightly wet with precipitation."

"Her face is very kind, and there's a soft, soothing aura around her. She's wearing a very formal looking long hemmed kimono that has drooping sleeves and delicate decorations of blue and white trailing down its sides."

"There's no sash tied around her waist, so you aren't sure how it's clinging to her body so effortlessly, but it looks like she can slide out of it at a moment's notice if she so desires."

"Her kimono hides her impressive F cup breasts and prevent even a single inch of her presumably impressive cleavage from showing, but do nothing to stop her erect nipples from poking against the silk."

"Her kimono shows off her shapely hips, her luscious rear, and her plump thighs as she moves, and you can see her dainty bare feet sticking out from just underneath its hem."

Strategy
Aiko is a Yuki-Onna, encountered on the Will side of the temple. She is fought on a snow-covered battlefield and insists on warming the player up. She will do this by any means available to her. Sexually, that is. She uses Temptation during her battle, and can force the player into stat-checks during certain stances. The player will be unable to start any penetrative stances due to her kimono being in the way, but this can be remedied by either Restraining or Charming her.

Using Pain moves on Aiko or avoiding her Temptation attacks will cause her to grow increasingly angrier, which is marked by the cold storm around her growing stronger. Once she has had enough, she will automatically knock the player down and stomp on their erection, forcing you to submit to her until she apologizes for snapping at you and embraces you with her kimono, leaving you snug and trapped with her. You will have to succeed a stat check to get out afterwards.

Once Aiko is defeated, the player can return to her boss chamber at any time and request a rematch.

The Frozen Room
While exploring the Will-Power Temple, you may stumble into Aiko's room, where she will tempt you into warming up with her. This event is essentially identical to her boss fight and has the same results.

Loss
After running out of Spirit, you are left cold and shivering on the snow. She will then wrap you in her kimono and preform a very warm and loving Paizuri on you.

Victory
Defeating Aiko will cause her to lie nude before you, allowing you to dominate the Yuki-Onna as she lovingly kisses you in response. However, you will lose Spirit every time you ejaculate. Fucking Aiko three times in a row like this will cause the player to lose all Spirit and be sent back to Town as if they had been defeated.

Defeating Aiko while in the Anal stance will lead to an alternate post-victory scene where the player thoroughly fucks her ass, much to her delight before she fades away, allowing you to continue your adventure.

Visiting Aiko
Once the player has cleared the Will Side, you can return to Bed-Chan's Rest Point and spend time with both her and Aiko. Here, you can have friendly conversation with her, inquiring about her species, her reason for being there, her obvious attraction to women and her love for getting her butt played with. Asking to cuddle gives you the option to do so with either Aiko or her and Bed-Chan at the same time; choosing the latter leads to a long scene where you have a threesome with them, being gently dominated between their incredible softness.

Asking Aiko for sex leads to a choice between vaginal, anal, a titfuck, gently melting you in pleasure (which will drain all of your Energy and most of your Spirit) or a threesome with Bed-Chan (different from the cuddle one). Once you inquire Aiko about Yuki-Onnas, you can also ask her to sculpt her body, which lets you choose between her art appearing more slim and elegant, or slightly more soft and plump.
