Lisanna is the younger sister of both Elfman and Mirajane, and is also a member of Fairy Tail, like her siblings her magic is Take Over. Her member stamp was on her upper left shoulder and now is on her left thigh. It is also very possible that Lisanna, Elfman and Mirajane operated in a three man group similar to Shadow Gear. She lost her life while trying to revert Elfman after his full-body Take Over went awry. He quickly lost control of himself and went on a rampage. Lisanna gave her life trying to calm him down and stop his rampage. How she actually was able to do this is unknown. The mental and emotional trauma that Elfman and Mirajane both experienced after Lisanna's death crippled their powers considerably. Mirajane lost her S-class rank and has not fought since. Elfman suffered major emotional damage and was incapable to cast his Full-Body Take Over spell for some time. When he did try casting it, a flashback to Lisanna caused him to lose concentration. When Lisanna was younger, she seemed to be very kind like Elfman and unlike Mirajane. She wanted to help Natsu Dragneel raise an unknown egg to see what comes out of it, being a little more knowledgeable in it than Natsu. After seeing a softer side of the usually flamboyant Natsu, she stated that he was a lot like her sister and joked that perhaps later she should become his bride which predictably freaked him out. It is shown that while the Earthland version of Lisanna is deceased, the Edolas version of Lisanna is still alive. Like her Earthland counterpart, she seems just as friendly and caring, as seen when she scolds Lucy for bullying Natsu and tells Jet and Droy not to pick on Elfman. When Natsu and Happy see her they both shed tears and tried to hug her in joy, this freaked her out. She doesn't seem to have the massive crush her Earthland counterpart has on Natsu. In chapter 199 and Episode 95, it is told that the Earth Realm Lisanna was sucked into Edolas and didn't die. After she was taken back to the Earthland by the reverse anime. She was found by PantherLily and taken to Natsu and the others. There she explained everything to them and went back to the Fairy Tail Guild.
Being a shy, timid girl, Haruka is set up with Takayuki by her friend, Mitsuki, while she is in high school. The two quickly become close, and develop an intimate relationship. She takes in an interest in collecting picture books. Very early on in the series, she is involved in a serious car accident and ends up in a coma. The main thrust of the story begins when she awakens three years later. She is afflicted with anterograde amnesia, and because of her delicate psyche, her family and Takayuki conceal the truth that three years have passed, which forms much of the tension in the series.

Casino King is the name that the Gambling King gives to any area where he can set up his rigged gambling games, which include dice games, card games against the King himself, and pachinko machines. It is typically little more than a small stall at a fair or festival, or some relatively sheltered spot in an out of the way position on the street, but when the King successfully "wins" the Tendo Dojo from Ranma in a rigged game, he converts it into a much larger version, taking advantage of its wide space and sturdy roof.
Nodoka is Ranma's loving mother. She hasn't seen him and Genma in over a decade though, when they left on their training trip. Stating that a doting mother would hinder Ranma's training, Genma made a contract with her to raise Ranma as "man amongst men", and if he failed, he and Ranma were to commit seppuku. However, because Ranma's curse makes him a woman half the time, they spent most of Nodoka's appearances hiding from her as Ranko Tendo and her pet, Mr. Panda. Nodoka's heart was constantly broken by knowing that she wanted nothing more than to see her son again. Eventually in the manga, she did meet Ranma and Genma and discovers their curses. However, she was more accepting than they expected. Mostly because she eventually began to suspect that Ranma and Ranko were, in fact, the same person. (Wikipedia)
Ryutaros (リュウタãƒã‚¹) is the fourth Imagin that gives Ryotaro his power, which allows for the transformation into Den-O Gun Form. His natural weapon as an Imagin is a shotgun named the Ryuvolver (リュウボルãƒ�ー). Though he is the last Imagin to appear, Ryutaros initially possessed Ryotaro the moment that Urataros did, and simply hid himself from the others. Ryutaros reveals himself in his form when he is attracted by Naomi's coffee inside the DenLiner. Ryutaros is most childish in personality with a love for drawing and animals. Ryutaros also appears to enjoy break dancing, to the point to that it is incorporated into his flashy fighting style. His personality is one of a fun-loving dancer/disc jockey and is the most dominant Den-O has. This recklessness also causes the most collateral damage, as he fires his gun aimlessly. When he possesses Ryotaro, he first asks "Is it okay if…?" (…ã�„ã�„?, …Ii?, usually "Is it okay if I beat you up?" or "Is it okay if I end it?") followed by "Your answer doesn't matter" (ç”ã�ˆã�¯è�žã�„ã�¦ã�ªã�„, Kotae wa kiitenai).He has the ability to control people simply by snapping his fingers. This tactic works with summoning the Machine DenBird as well. Originally, Ryutaros possesses Ryotaro after being promised the title of become the DenLiner's conductor by Kai, who also gives the Imagin a ticket, on the condition that he destroys Ryotaro. However, because he does not wish for Airi to cry, Ryutaros decides not to destroy Ryotaro. The only individual he will listen to is Airi, whom he affectionately calls "sis" (ã�Šå§‰ã�¡ã‚ƒã‚“, onee-chan, Ryotaro only calls her the more formal "sister" (姉ã�•ã‚“, nee-san)). Because he knows that Airi has loved Yuto Sakurai, and from faulty advice on love from Kintaros, he becomes jealous of Yuto and wishes to show that he is stronger than him. But when Kai takes matters in his own hands in killing him, combined with realizing how he and Airi can not to be together, Ryutaros matures a bit to cope with fading away while eventually mustering courage to fight in the final battle against Kai. He usually refers to Urataros, Kintaros, Sieg, Teddy respectively as "Turtle-chan" (カメã�¡ã‚ƒã‚“, Kame-chan), "Bear-chan" (クマã�¡ã‚ƒã‚“, Kuma-chan), "Bird-san" (トリã�•ã‚“, Tori-san), and "Blue Bear-chan" (é�’クマã�¡ã‚ƒã‚“, Aoikuma-chan). However, he excludes Momotaros as he is not based on an animal and Momotaros does not understand him like the others do. He is referred to by the others as "Ryuta" (リュウタ, RyÅ«ta?). After this initial arrival on the DenLiner, he is rarely seen without a pair of headphones over his head. One of the TarÅ�s, Ryutaros's basis is unclear as early promotional material stated his form to be based on the legend of Tatsu no KotarÅ� (Taro the Dragon Boy) while TV Asahi's website for Den-O states that his form is based on Ryotaro's mental image of dragons. One of the Imagin Anime shorts discusses Ryutaros's possible namesake.
