Aiha

Aiha is a woman with long hair often styled with a ribbon.

She wears Western-style armor with a long skirt.

In the anime, she is shown to have light pink hair and blue-violet eyes.

When she turns into a Regalia armor, her skirt is so long that Bishamon sometimes steps on it by accident.

Aiha used to be confident and proud as Bishamon’s main defense.

After being replaced by Tsuguha, she feels jealous and insecure.

She tries hard to get Bishamon’s attention but ends up getting frustrated.

Aiha’s jealousy leads her to bully Tsuguha by, for example, cutting Tsuguha’s hair.

Even though she tries to hide her trouble with medicine, Aiha feels guilty for her actions.

She really likes manga and drawing, especially about Bishamon and Yato.

Aiha served as a Regalia for Bishamon for over half a century.

She was once Bishamon’s main armor and defender.

As new Regalias joined, Aiha was replaced and started feeling left out.

She spends more time in Takamagahara now and rarely joins battles.

As Bishamon’s Regalia, Aiha has extremely high defensive power.

Her armor form protects Bishamon in fights.

She uses Western-style armor with a long, protective skirt.

She is also creative in making manga drawings.

• Bishamon: Aiha is deeply loyal to Bishamon and wants her attention and approval.
• Tsuguha: Considered a rival at first, Aiha bullies her but later becomes friends, sharing girl talk after reconciling.
• Kugaha: Kugaha gives Aiha medicine to hide her distress but secretly uses her in his plots.
• Kazuma and Hiyori Iki: Aiha saves them when she realizes she was being used.
• Yato: Aiha mistakes Yato and Bishamon as a romantic couple after seeing a kiss, and she draws stories about them.

• When she was still Bishamon's armor, her skirt was so long that Bishamon would sometimes step on it.
• She likes drawing and fills exchange notebooks with shoujo manga-style stories, especially about Bishamon and Yato.
• Kazuma forgot to continue the exchange notebook after her manga entry, so she did not get it back.
