Suwako Moriya

Due to Suwako being Sanae's ancestor, it is implied that she used to have a partner long ago and has given birth before which over a few millennia, lead to Sanae. Though this partner is never usually mentioned as they are from an era long ago

Kanako Yasaka - While Suwako claims to still hold a grudge against Kanako for taking over her shrine, her own faith actually increased as a result. By now they've become good friends and continue to work and live in the same shrine.

Sanae Kochiya - Sanae acts as a wind priestess under Suwako and is able to summon her. Sanae is also Suwako's descendant meaning they're blood related. (Suwako may also have a slight tendency to act slightly motherly towards Sanae)

Utsuho Reiuji - She was presumably present when Kanako presented the Yatagarasu to Utsuho.

Mishaguji - Suwako was the one who tamed the Mishaguji, and she's the only one who can control them.

Hisoutensoku - It's implied that Suwako was involved in Hisoutensoku's construction.

Incident Solvers - Since she was part of the Mountain of Faith Incident, Suwako has run into Reimu and Marisa while they were solving said incident. Despite this, Suwako holds no grudge against the two and since they're also friends with Sanae, she sees them as friends as well.

Suwako wears a short simple purplish-blue dress with a frog print design based on a panel from the first Chōjū-giga scroll, as well as large white sleeves stitched onto the torso which usually go over her hands, and a white collar. She has medium length blonde hair, grey eyes, a light brown wide-brimmed hat with two frog eyes on the top, white thighhighs and black shoes.

She's normally depicted as looking petite and very young. But despite her younger appearance, she's one of the oldest gods in Gensokyo.

It is revealed that during ancient times, Suwako was a ruler of a small kingdom and controlled the Mishaguji, who were curse gods that had obtained enormous amounts of faith, cursing birth, harvests, militaries, and many other things. Only Suwako was able to tame them. However, gods from the Yamato (Ancient Japan) invaded her kingdom, saying that they were going to unify all the kingdoms to create a single country known as Japan. Unwilling to let this happen, Suwako resisted and fought with the finest steel weapons of the time. However, Kanako held out a thin vine, and Suwako's large steel arsenal instantly rusted away. Suwako realized the difference in their divine powers and her defeat; she graciously forfeited and relinquished her kingdom.

Unlike Kanako, who is technically a Divine Spirit and once had a human form, Suwako is one of the Yaoyorozu no Kami, and thus consists purely of faith. This means that as long as she has people who have faith in her, she's as godly as it gets. She also controls the Mishaguji, which is one of her main sources of faith from humans. When a portion of her spirit is enshrined, she can take on the form of a frog. In this form, she can grant various blessings, such as safe travel, financial upturn, and transfiguration.

Ability to create earthliness - Suwako's ability specifically refers to the element of Kun (坤), one of the eight trigrams in Taoist philosophy that means creating Earth. Kun is exactly the pinnacle of the native god and is associated with acceptance, devotion, subtlety, flexibility, and reacting to others rather than acting first. In short, she has the ability to manipulate earthly elements such as water, earth, plants, and even some different airs as long as they're produced by organic things from the earth like plants

Due to her ability to manipulate earth and minerals, she also possesses iron rings as weapons which she usually throws at her opponents

Suwako typically acts friendly and cheerful though she feigns ignorance, Suwako is just as capable of scheming as Kanako, if not more. In contrast to Kanako, Suwako is more laid back and mischievous. Despite her young look, she is a god that has lived for over 2,300 years and is wise and even cunning. She enjoys competing against others, and loses gracefully. Combined with her rarely leaving the shrine, her intentions can be hard to read. She doesn't come forth of her own volition often. Whether it is because she is bad at marketing faith by herself or some other reason is one of the mysteries of the Moriya Shrine.

Suwako Moriya is the original goddess of the Moriya Shrine that now officially belongs to Kanako Yasaka but in Suwako's words she handles most of the divine services while Kanako and the shrine maiden, Sanae Kochiya, handle the "sales" and the duties of gathering faith.
