Yes

Samus continued rubbing her bulging belly. She could feel the strength of her daughters. If she carried them, they’d be unimaginably powerful. If they were allowed to be born they’d be stronger than her both physically and spiritually. And even as they grew sapping the strength from her body, she could feel that she would grow stronger spiritually as well.

“What side effects could there be?”

“Unclear.”

Samus weighed her options, but it was already obvious to her. She felt a warm, growing power flowing through her and the babies.

“Install Miko Upgrade. Permanently.”

Samus felt the chip disintegrating into microscopic particles, entering her blood and penetrating her DNA. She felt a building and warm pleasure as her hips and thighs expanded to accommodate her daughters while a thin layer of fat built up around her butt leaving it just noticeably larger. Her chest felt the same building pleasure as her breasts grew three sizes and her mammary glands began to produce milk. The final change came as the particles rushed up her neck and coursed through her brain, installing fragments of the knowledge she needed to fit in as a Miko, but only fragments.

Samus came to with her body fully transformed and her chip slot empty. She rose gingerly from the table, sandals clacking softly against the steel floor. “Computer, mirror.” She said. Her accent was noticeably thicker. Soon enough the computer retraced a steel wall covering a mirror in the room and let Samus see herself. Her body was perfect. She continued rubbing her tummy and triplets until curiosity came over her and she lifted up her red skirt. It had begun to ride up her growing belly as she changed but the growth seemed to slow dramatically. As she left up the hem she studied herself in appreciation. With one hand she rubbed her tummy and daughters. After a minute however, her eyes drifted downwards and happened over her underwear. The white garment was certainly similar enough to her old panties with one glaring difference. A Japanese character was printed over the front. After focusing on it, she realized it finally.

“Kami? Why would something like that be printed there?” She giggled. As though the character for the divine belonged over her intimacy.

She lowered her skirt again and took the top of her robe off of her shoulders to study that as well. Every blemish and scar was gone. Her breasts had doubled in size, at least, tucked comfortably behind a light pink maternity bra. They became even more impressive relatively because her new body wasn’t an inch over a meter and a half tall. There was nothing physically intimidating about her anymore. The only thing that hinted to her that some of her power was still there was that despite now being roughly six months pregnant with triplets, she didn’t feel anything more than a slight weight or shift in her center of gravity. Content with her choice, she covered herself again and walked back upstairs to the vacuous room with all of the upgrade chips.
