Saiko Bichitaru

Saiko Bichitaru (美千足 最子 Bichitaru Saiko) is a character from a generic dating sim brought to life by Fishy Boopkins in order for him to have a real girlfriend, but she turns to suffer from minor mental instability and evil intentions. Though introduced as a temporary antagonist, she has more recently been more of an anti-hero, become a protagonist, and part of a latest main roster of SMG4 Poster.

History
In SMG4, she appears in SMG4: Doki Doki Mario Club where she comes to life when Fishy Boopkins uses Kamek's wand to make her come to life, but in real life, she becomes extremely jealous, destroying anything that might get between her and Fishy, including Fishy's waifu body pillows. This, of course, leads to Fishy dumping her, and her going insane to him and the main gang. She is later stopped and both her and Boopkins are forced to let go.

With her reappearance in SMG4: Mario Battle Royale, Saiko tried to attempt to defeat SMG4 and Mario with her Minigun Machine. When Fishy Boopkins was about fall, she revealed herself that she still has feelings for Fishy Boopkins and wanted him back dating as she tries to save him from falling off a cliff; although she appears to have gone tsundere since her debut.

Saiko makes the antagonist again in SMG4: Final Fantasy Mario as the Commander of the Milita Base. Mario and SMG4 are forced to explain to Meggy that she used to be Fishy’s Ex and that she’s crazy. She states that her goals are to rid the world of the pretty, then become the prettiest person. Mario then diagnoses that Saiko has Schizophrenia. Retorting that she is not crazy, but heartbroken, she orders a squad of Cactite to rid of the party.

SMG4 uses magic to summon walls to block off any damage. Now surrounded, Meggy comes up with a plan. She tells Mario to use his Buster Sword to send herself airborne just above the wall so she can shoot down the Cactite. Saiko, now very unsatisfied, pulls out a ray gun and destroys the wall surrounding the party. Everyone, now on the ground, she tells them to run back home, then fires more lazors on the team. Mario tries to dodge the oncoming fire but is knocked backed, SMG4 and Meggy try to counteract by throwing their inventory at Saiko, who is able to dodge anything they throw.

Mario then reappears by flanking her right and makes her go airborn and drops her. SMG4 demands that she gives up. But it appears that Saiko hasn’t finished; she whistles up a flying mech as everyone stares in bewilderment and confusion. The Commander says it time to end this, SMG4 retaliates by throwing fire; it does absolutely nothing. Saiko finds this certainly cute, then fires Banzai Bullet Bills. Mario tells her off but is blasted once again, SMG4 erects a glacier to protect himself and Meggy, who comes up with another plan. With the help of SMG4 and Mario, she makes a Banzai Bill flip and hit the flying mech, causing it to explode. An unconscious Saiko is last seen being thrown through a portal by Mario.

She reappeared in SMG4: The Mario Channel - Mario's Jackass where she receives a call from Mario to go to the park. When she got there, Mario tells her saying that he's doing a TV show and needs her to be a part of it, which she was excited since she thought he needed a model, however, Mario reveals she is part of his next challenge where he turns the turret on which would fire at her. Later in the video, she and the others get revenge on Mario with the same stunts pulled on them, as she was waiting for him in a bunker with a sentry who fired at Mario. At the end of the video she asks Mario if he has anything to say to people he pranked, attempting to make the plumber apologize, but he then said "Eat my Mario P*nis" which she makes the sentry fire at him again.

In SMG4: Luigi's Lesson, she is seen tired of being feared by everyone because of her behavior and Luigi tries to teach her to be nice but fails to do so. A little later, together with Luigi, she races Mario to the hospital when he gets a heart attack after eating 500 hot dogs. Luigi was happy to see that Saiko did know how to be nice even though she claimed she didn't know what he was talking about and after delivering Mario to the hospital, Luigi thanks Saiko and hope that they could be friends, bringing Saiko a smile on her face and then drives away on her motorcycle.

She reappears in SMG4: The Mario Hustle as a main character/protagonist/good person who was selling rocks since SMG4 accidentally bought a million of them, and SMG3 ended up buying 2 million, who was convinced he'd be cooler than SMG4 by doing so, therefore Saiko Bichitaru become the most seller in SMG4's Twitter Post Picture.

Appearance
In the typical anime style, Saiko is an incredibly tall and skinny teenager with a curved figure and large bust. She has pink, curly hair with two different colored highlights at the tips: purple highlights on the right side, and yellow highlights on the left. Her eyes are purple and almond-shaped, with thick, curly lashes on the ends.

In terms of attire, Saiko is always seen wearing a tan jacket with a black tube top underneath, a dark-brown miniskirt, a black belt with a skull buckle, black leggings, and light-grey casual shoes. She wears a skull-and-crossbones pendant around her neck, and her hair is tied up in twin tails with two red bows.

In SMG4: Final Fantasy Mario, Saiko also wears a black burette, which is detailed with white trimming, a red gemstone embedded in gold, and white feathers on the side.

In the video SMG4: The Mario Hustle, Saiko wears a Atwood Sandy Palm Hat and a red short bow tie as her business outfit while holding her leather steel briefcase.
