Seiko Ayase (あや せい Ayase Seiko?) is a major supporting character of the manga series Dandadan.

She is a well-known spirit medium who also goes by the name Santa Dodoria (ドドリア三太 Dodoria Santa?) and the grandmother of Momo Ayase. While performing her duties, Seiko provides support to Momo and her friends as they become involved with spirits, aliens, and other paranormal activities.

Appearance[]

Despite being a grandmother, Seiko has the appearance of a slender woman in her prime. She possesses long white hair that she generally ties up in a large top knot, wears glasses, and can occasionally be seen smoking at times. On top of her youthful appearance, Seiko has been noted for her beauty that she claims others might go so far as to describe her as being bewitching. Due to this, many have mistaken her to be Momo's mother and leave them in shock once they learn her true relation to the girl. In terms of height, she is shown to stand no taller than her granddaughter.

When out in public, Seiko wears an open large button sweater that reveals her cross-strap top, a jacket with a symbol on the back, hoop earrings, and sandals. When at home, Seiko prefers to wear a tank top, shorts, a haramaki, long socks, and arm warmers.

As Santa Dodoria, Seiko wears a mask, sharp finger tipped gloves and a cloak cover up her entire body.

In the past when Momo was a little girl, Seiko wore the respectful attire of a shrine maiden and had her hair tied in a regular ponytail.

Personality[]

Seiko has a phlegmatic personality and a highly uncouth manner of speech. At the same time, she is selfless and empathetic to help others in need if it's within her power, with the greatest example being her taking people into her house if they need a place to stay. As such, she follows the concept of "being in it together". Instead of accepting Okarun's generous compensation for looking after him while he was cursed by the Turbo Granny, Seiko told him that the only way he could repay her was to help other people who were in trouble. When involving herself with children, Seiko believes that, as an adult, she should be able to shoulder their burdens to allow them to be free to do what they want in life. Because of this, she felt saddened that she was unable to honor Jiji's wishes to help him keep the Evil Eye under control in order to spare the yokai from being exorcised. While willing to help others, Seiko is too proud to admit when she needs help herself or burden others with her problems, having at first refused Okarun and Mr. Mantis Shrimp's offer to help rebuild her house when it was in ruins after the Evil Eye's stay.

Seiko can also come off as being a bit immature, such times being when she teased Momo about having a crush on Okarun, due to him having the same name as Ken Takakura, and having her granddaughter make a Hiroshi Abe impression in exchange for having to buy her a new school uniform. Despite this and her unladylike way of speaking, Seiko can act polite if she feels that she has made a mistake that involves the well-being of others. This side of Seiko is seen as being rare and out of character to those who know her well. Though she claims that she has never been moved by emotion, Seiko subconsciously favors those who compliment her, such as her youthful appearance which she takes great pride in.

As a spirit medium, Seiko follows the rules of coexistence between the living and the dead, which is to not disrespect the dead and send them to the afterlife, by using force if necessary, if they choose to attack the living.

Seiko has a passion for food, believing that it should not be taken lightly since "living begins with eating". As a cook who occasionally serves food for Momo and her acquittances, she finds it delightful to see a person who knows how to eat by filling up on the food she makes and even becomes motivated to make more to further satisfy their appetite. On the other hand, she dislikes picky eaters.

While a believer in spirits, Seiko is a disbeliever in UFOs or aliens. Even after Momo brought home Mr. Mantis Shrimp as proof, Seiko only saw him as being a kappa and did not think much of the alien's spacecraft after abducting a cow. She enjoys watching television shows, which is the only thing that brings her a sense of joy and laughter in life.

Background[]

Seiko took in her granddaughter Momo when she was little and wanted to pass on a little of her ways as a spirit medium, instructing her to perform a daily spell routine that would potentially help her to release her ki. Following her grandmother's instructions, Momo faced bullying from children whenever she performed the daily spell in public. This then resulted in Momo blaming Seiko for the mistreatment and accusing her of being a fraudulent spirit medium, a claim that deeply affected her. Eventually, their relationship began to heal after Momo apologized to Seiko.

Abilities and Powers[]

Natural Abilities[]

Immense Strength: Seiko has impressive strength, being able to put enough physical power into her bat to knock down the Evil Eye and create a crater on the ground with one swing.

Immense Speed and Reflexes: Seiko has impressive quick reflexes, as she was able to avoid being hit by the Evil Eye's attacks at close combat.

Intelligence: As a spirit medium, Seiko has a clear understanding of spirits and how to protect oneself against evil spirits.

Supernatural Abilities[]

Spiritual Awareness [v · e]
Seiko is capable of seeing spirits, such as earthbound spirits and yokai.
Clairvoyance
Seiko has demonstrated to be clairvoyant using a crystal ball, as she was able to accurately read into a celebrity's secret background.
Power Borrowing
Seiko has the ability to borrow power from gods that reside within regions, with her main region being Kamikoshi City where she lives.
Mystic Barrier

By borrowing power from gods, Seiko is able to erect mystic barriers that are able to exorcise evil spirits, or anyone cursed by an evil spirit for that matter. This is done with the use of her charm nails and talisman. The effects of the exorcism appear as flames that burns away the evil spirit until they are completely turned to ash. The lethality of the barrier can increase if more than one nail is placed on the ground. Since her barriers are only effective if the god is around, Seiko is limited to exorcising evil spirits within the perimeter of the region she has borrowed power from.

Usage
Magic Barrier explanation

The two ways the mystic barrier can be used.

Using the slidable pencil tip at the top of Nessie to draw a large circle on the ground, Seiko can create a barrier large enough for one person. When a charm nail is placed within the drawn circle, Seiko can create a barrier that protects her from any evil spirits that might attack her. When placed on the outside of the drawn circle, Seiko can trap the evil spirit and leave them at her mercy.

Seiko is also able to use the barrier for offense as well, as shown when she stopped the Turbo-Granny possessing Okarun from eating Momo by placing a small barrier on a brick and using it as a throwing weapon, causing the barrier's flames to activate and engulf the yokai once made contact.

Power of Words
(言霊 Kotodama?)
Power of Words
Seiko is able to harness the Power of Words, referring to the power to alter reality through one's words that are said with conviction behind them. In a training session with Momo when she was little, Seiko demonstrated this ability on a sandbag to have it sent flying with a swing of her bat by shouting out the word "Nessie", having put enough feeling into the word after naming her bat Nessie from Momo's answer as to what she believes is the strongest creature in the world.


Weapons[]

Nessie (ネッシー Nesshī?) [v · e]
Nessie (Bat) Infobox

Seiko wields a bat with the words "Power of Nessie" (ネッシーの力 Nesshī no Chikara?) engraved as her signature weapon. The bat gets its name from the Loch Ness Monster after Seiko asked Momo in the past as to who she thought was the strongest creature in the world was in order to demonstrate how to use the Power of Words on a sandbag.

Coupled with Seiko's impressive strength, the bat can cause great damage to opponents, and with the Power of Words applied, she can send her targets flying effortlessly with one swing. The bat also has a slidable pencil tip used for Seiko's barrier magic.

Talisman
Charm

Talisman that are used to cast Seiko's mystic barriers and detect any evil spirits nearby. The power of a talisman will be used up once it has been activated and will be darkened to signify this. Seiko has placed talisman in her home to ward off any evil spirits that may enter.

Charm Nails
