The last issue of Akiko came was published in March 2002. On Mark Crilley's blog, he stated that the comic has gone out of production. He continued to write novels in the Akiko book series, with the tenth and final novel released in 2008. He has recently created a new book series about extraterrestrials, "Billy Clikk", and a manga series, "Miki Falls". The first four books borrow their storylines from the comics (detailing Akiko and her team's quest to rescue Prince Froptoppit from the sorceress Alia Rellapor), while the others introduce original plot lines. In "Akiko: The Training Master", Akiko is somewhat older and drawn to resemble a teenager rather than a child. Some reviewers referred to the books as a fun adventures appropiate for younger readers, with some describing them as being free of gender and racial bias. The first book, "Akiko on the Planet Smoo," begins when 10-year-old name Akiko is removed from Earth and brought to Planet Smoo because its King Froptoppitt believes she can save his son. There, Akiko is introduced to her fellow questers (Mr. Beeba, Poog, Spuckler Boach, and Gax). The next three books depict a series of adventures, arguments, mishaps, and exotic alien places, creatures, characters, and food, until they reach Alia Rellapor's castle. The next three books contain further adventures ("Akiko and the Alpha Centauri 5000" centered on Spuckler while "Akiko and the Journey to Toog" focuses on Poog's backstory) but Akiko always begins and ends the novel on Earth. In "Akiko: The Training Master", set some years later, Akiko and her friends attend a special academy to become official guardians of the Planet Smoo. Other items:
