Kotaro was pretty much supposed to be your average boy, worried about the pressures of education while enjoying a simple life with his friends. Much to his despair, he one day finds the overly cheerful Misha at his door, asking to be friends out of nowhere. Even more shocking is that Misha is an apprentice angel, yet she does more bad then good. Along with Kotaro's school friends Takashi and Koboshi and the so called devil Shia (once again being able to do more good then bad), the group of friends spend their days getting into all sorts of adventures and troubles. Based on the manga by Koge-Donbo.

As a child, Aoi Yukimura adored mountains and was passionate about climbing. However, a playground accident has since left her afraid of heights, turning her toward indoor hobbies. Unfortunately, now a shy and timid first-year high school student, Aoi has become so absorbed in these pastimes that she can barely socialise with others, leaving her practically friendless. It’s only when she runs into the lively Hinata Kuraue, an old friend from her climbing days, that things start to change. Impulsive and high-spirited, Hinata insists on having Aoi join her in all sorts of climbing activities. Though reluctant at first, Aoi quickly finds that her time with Hinata brings back fond memories of their childhood and soon decides to start climbing again. As the return to her past hobby starts to bring her out of her shell, Aoi finds herself gaining close friends, taking on new challenges, and continuing to find her own encouragement to climb.

The Layzner OVA serves as an alternative version of the TV series. The first episode, titled "Eiji 1996", recaps the first part of the series (episodes 01-24). The second episode ("Le Caine 1999") takes place after a time skip, and contains episodes 26 through 37 (episode 25 of the TV series, being a recap itself, is skipped here). The final episode, "Seal 2000", is an expanded version of the final episode of the TV series (38) and features new animation and a longer epilogue.

Kazamatsuri, a modern, well-developed city renowned for its burgeoning greenery and rich Japanese culture, is home to Kotarou Tennouji, a high schooler least privy to the place's shared values. Content to fill his pockets with frivolity, the proud and nosey boy whiles away his time pestering the self-proclaimed delinquent Haruhiko, and indulging in his amorous feelings toward the oddball Kotori. Equipped with the superhuman ability to permanently rewrite any part of his body to multiply his strength or speed, Kotarou is naturally drawn to the supernatural. One special meeting with the lone member and president of the Occult Research Club, the "Witch" Akane Senri, leads to Kotarou reviving the Occult Club by recruiting Kotori and three other members: the clumsy transfer student Chihaya, the strict class representative Lucia, and the unassuming Shizuru. As Kotarou unveils hidden secrets of each member of the Occult Club through their shared adventures, he will inevitably encounter a fate that only he might be able to rewrite. [Written by MAL Rewrite]
