Ikeno Koi (池野 恋) is the amazing writer and artist who created the world of Tokimeki Tonight. She was born on April 16th, 1959 in Iwate prefecture, and made her debut as a manga artist in 1979 with Happy End Monogatari. She continued to publish many stories in Shueisha's Ribon magazine until about 1999, and has since worked chiefly in Cookie, Shueisha's shōjo magazine for older readers. Some of her other popular works include Nurse Angel Ririka SOS (original concept by Akimoto Yasushi) and Heroine ni naritai.
Most recently, she drew the autobiographical series Tokimeki manga-michi, which was highly well-received by fans. She has also published short stories in Comic Iwate, a local magazine for manga artists from Iwate prefecture. She still resides in Iwate, and is married with two children.
Below, I've compiled a list of her published work outside of Tokimeki and its various spin-offs.
Chotto otogibanashi (1980)
A collection of five early one-shots. This was previously out of print but now available as an ebook.
Chotto otogibanashi (1980, Ribon July issue)
The story of a girl who dreams of becoming a children's book author and meets a devil and an angel. It has comedic moments but also dramatic moments that reminded me of the later parts of the Ranze arc.
Happy end monogatari (1979, Ribon new year's special issue)
Ikeno made her debut as a manga artist with this one-shot. It's a comedy about a guy who gets stalked by a girl who thinks they're in love with each other, and agrees to date her when her father tells her she doesn't have long to live.
Doyō no gogo wa hōzue tsuite (1979, Ribon summer special issue)
A romantic story about a girl who falls in love with a guy who called her phone accidentally. I think this is the most typical shōjo manga/otome-tique story I've read by Ikeno; the emphasis on romance, the quirky way the hero and heroine meet, and the tragic past of the hero really reminded me of Tabuchi Yumiko's manga.
Telepathy ni goyōjin! (1979, Ribon November issue)
A historical romantic comedy about a Meiji-period young man who falls in love with an young aristocratic girl and studies telepathy in order to tell her how he feels. It's very comedic, and you can tell Ikeno incorporated fantastical elements in her stories from very early on.
Tonari no one pattern (1980, Ribon March issue)
The story of a girl who lives next to a father and son family who are trying to develop a time machine.
Mai-chan non stop (1981)
A tankōbon collecting all three chapters of Ikeno's first serialized manga Mai-chan non stop, as well as an unrelated one-shot. This is currently out of print.
Mai-chan non stop (1981, Ribon January-March issues)
Mai travels to Tokyo to find Shū, a childhood friend she promised to marry when they grow up, but when she finds Shū, it turns out he has joined the yakuza. Will Mai succeed in capturing Shū's heart, and will his yakuza gang be able to remain pacifists when a rival gang starts invading their territory?
Ojama-mushi 1/2 (1981, Ribon July issue)
High school girl Saka has a best friend, Natsumi, who doesn't seem interested in boys at all. But when a French exchange student moves in with Saka's family, it seems that both Saka and Natsumi start developing special feelings for him... but are those feelings love?
Mechanko kyōshitsu (1982)
A tankōbon collecting all five chapters of Ikeno's second serialized manga.
Mechanko kyōshitsu (Ribon September 1981-January 1982)
A school comedy about a high school girl and her big sister who is shy and very traditionally feminine, but also incredibly strong and convinced that she will never be able to marry because of this un-womanly feature. The protagonist tries to set her sister up with her teacher while also dealing with issues of her own.
This was previously out of print but now available as an ebook.
Heroine ni naritai (1991)
A tankōbon collecting all three chapters Heroine ni naritai and a one-shot. The original tankōbon is out of print, but is now available as an ebook.
Heroine ni naritai (Ribon January 1990-March 1991 issues)
A short series that ran in Ribon between the Narumi and Aira arcs of Tokimeki. This is my favorite work by Ikeno outside of the Ranze arc of Tokimeki: it's a collection of three self-contained short stories about three best friends who each struggle with their personal issues as well as to find love. There are no fantasy elements to this story, which is rare for Ikeno, but all her characters are well-developed and likeable and you can't help but become engrossed in their personal struggles. More than any other work, I think this series shows Ikeno's skills as a shōjo manga writer. The art is also fantastic.
Kimagure time machine (1982, Ribon April issue)
An old one-shot never previously included in a tankōbon. It's a romantic comedy about the heroine's father, a scientist, creating a time machine and bringing an Edo-period samurai to the modern world.
Nurse Angel Ririka SOS (1995-1996)
A series that ran in Ribon concurrently with a TV anime developed based on basic ideas by Akimoto Yasushi. It is believed that Ikeno was instrumental in developing the characters and designs of the series. It's the story of Moriya Ririka, a fourth-grader who transforms into the Nurse Angel in order search out the "flower of life" and save the world from the evil Dark Jokers. The series was previously out of print but is now available as an ebook.
Oshiete Nanoka (1996-1998)
This is Ikeno's only original long-running series outside of Tokimeki and its spin-offs. It's the story of four siblings who find out they have a secret connection to a fantasy world. It was previously out of print but is now available as an ebook.
