Saiko Bichitaru

Saiko (Japanese: 美千足 最子, Bichitaru Saiko) is a character from a generic dating sim brought to life by Fishy Boopkins. 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.

Although in SMG4: Mario Battle Royale, it's revealed that she still has feelings for Fishy Boopkins, as she tries to save him from falling off a cliff; although she appears to have gone Tsundere since her last appearance.

She reappeared in SMG4: The Mario Channel - Marrio's Jackass where Mario bumped into her, she tell him to watch where he's going, Mario then trick her by saying that he's doing a movie, and need her to be part of it, wich she was excited to be in, but of course she fall in the trap he put has he make machinery fire at her and exploded, she and the others then get revenge on him, has she was waiting for in bunker with a sentry who fired at Mario, at the end of the video she ask Mario if he has anything to say to people he pranked maybe tried to force him to apologies, but he then said >Eat my Mario Penis" wich make the sentry fired at him again.
