In order

Asaji

Mother of Saizo and Kaze

She’s from the same clan as Kagero, though I’m not quite sure how they’re related

She’s alive and well during the events of Fates. The downside is she can outlive her sons, but if all wends well she gets to meet her grandchildren.

She served under Ikona until her boys were old enough to begin training, from there Asaji oversaw their training.

Saizo IV

Father of Saizo and Kaze

Served Sumeragi, naturally.

Was killed during one of the attempts to rescue Vaiana.

Toshizo Morine

Father of Souji and Hana

Served Sumeragi

Was gravely injured during the Cheve summit and died of his injuries before the night was out.

Took his wife’s name upon marriage

His son, Souji wears his armor

Chizuru Yajiri

Of Hoshido’s political figures, Chizuru is the youngest, barely into her twenties

She’s related to Setsuna and Reina

Kagura Nocho

Mother of Tsubaki

She a bitch

Used Cordelia as a base intentionally to explain a non-Selena Caeldori

Miaka Nocho

Younger Sister of Tsubaki

Pretty much a headswap of Cynthia. This was intentional.

Old friend of Sakura and Hana.

Alyss Ceallach

I actually do have a bit to say about her but that’s venturing into spoiler territory

Hilda Di Maio

Recolor of NPC. Why fix what ain’t broke?

Gameplay-wise she’d be like Nils and Hannah from Binding Blade

Mairin Gethen

First Princess of Nohr

Killed in an unprovoked attack from Hoshido, lead by Hinoka

Remembered fondly by Vaiana

Adelina Gethen

Fifth Princess of Nohr (I think)

One of Azura’s tormentors

Shares her mother with Akinli, the third prince
