-Name: Lusamine... Balsamine is the German word for Impatiens.

cheerfulness, impatience, short-temperedness, hasty resolution. Etc.

-Appearance: So youthful that she looks to be in her 20s.
A beautiful woman with striking looks.
She wears mostly white clothing, but unlike the girl, this is meant to hide her inner ego.

Character: The final boss of this game.

Her goal is to protect the Pokemon she likes (including those from other worlds).
She is afraid of her own warped love and her own unique love.
She is convinced that she can lead others in the right direction, and therefore forces many things on others. She is unable to refuse because she believes this is good.
The only daughter of the founder of the Aether Foundation. She was born in the latter years of the founder's life, so she was very spoiled. As a result, she believes that everything will go her way. The strength of this feeling allows her to act like a queen, and is the driving force behind her subjugating those around her.
A person with a strong possessiveness. She gives the impression of a child who cannot control her ego having grown up.
She has a strong ego and is too immature to act as a parent.

She prioritizes being a woman over being a parent.
The girl's brother is her decoration, her supporting role. On the other hand, the girl, who gives off a somewhat dull impression, sees him as someone who is unlikely to be a supporting role, and has no interest in him.

Protecting Pokemon is her kind gesture, but it is self-righteous, and moreover it is a kind of collecting act to satisfy her hunger.
Because protecting Pokemon at the foundation is an act of kindness, it is difficult to change her mind, and if you try to persuade her, she will consider you the enemy.
Having learned of the existence of Ultra Holes (another world) and the Pokemon (beasts) that reside there, she is determined to protect those as well.
She also wants to protect her neighbor's Pokemon, trying to get them by using Team Skull, with whom she is in collusion behind the scenes,
putting her own desires above good and evil.
Once she loses interest in someone, she pretends they never existed.
She has no interest in the girl's brother, who has left the foundation representative.
She is so uninterested in him that she cannot even remember him, even when the girl's adoptive parents give her updates. However, without realizing it, a void has formed in his heart, and he selfishly becomes obsessed with protecting Pokemon, and tries to admire the protagonist as a compensation for the disappearance of the girl and her brother.

As a result of fusing with the protagonist in his favorite clothes,
is it a roundabout revenge on the girl he has forgotten?

As a result of fusing with a Beast (a parallel Pokemon), his ego goes out of control, and he tries to protect all Pokemon, becoming hostile towards the protagonist and his friends.

In the scenario after completing the game, he leaves the Alola region to treat the aftereffects of the Pokemon fusion. This becomes the reason for his separation from the girl.
This is linked to the fact that Masaki from the Kanto region fuses with and separates from Pokemon using a teleportation machine.

*A metaphor for parents, or people who cannot become adults at all.

Lusamine is back in a sygna suit that shines. Together with Necrozma and Solgaleo, she unleashes her true strength to protect humans and Pokemon alike.
