Ikeda, Riyoko

Optimistic, 16-year-old Nanako Misonoo anticipates a blissful experience at her new high school. Enrolling alongside her best friend Tomoko Arikura, she is confident that her freshman year will be exciting and filled with pleasant memories.

However, upon entering the prestigious all-girls Seiran Academy, the wondrous school life Nanako had envisioned quickly vanishes as she is inducted into one of the school's most elite clubs, the Sorority. Normally only accepting the wealthiest and most prominent students, Nanako—who is neither rich nor well-known—is rumored to have cheated the selection and becomes a target of bullying from her envious peers. To make matters worse, she gradually becomes involved with Seiran's most popular students, the "Magnificent Three," comprising of the disconcerted pianist Rei Asaka, the competitive tomboy Kaoru Orihara, and the dignified Sorority President Fukiko Ichinomiya.

As a result of her abnormal situation, Nanako begins documenting her daily life in the form of letters to her former teacher, Takehiko Henmi, whom she fondly refers to as "brother," all while striving to find peace amidst the turmoil that is Seiran Academy.

Sakura Namiki

さくら並木

Ichijo, Yukari

Maya's Funeral Procession dates back to 1972; Ichijo's style is very different here, a combination of the quickly evolving shoujo style still very influenced by Osamu Tezuka's designs and of the blockier Gothic horror style reminiscent of woodcuts. The blacks are very solid, the whites are very bright; there is some stippling and cross-shading, but it all looks hand-drawn rather than screen-toned, and the panel layouts are just gorgeous.

On the way to her family's new country house, innocent young Reina notices a tall, dark, striking woman standing in the shadows. Soon, neglected by her parents, Reina falls under the spell of the mysterious Maya ... but family secrets may destroy any chance Reina has for happiness. This is one of the earliest examples of shoujo-ai (girls' love or lesbian romance) in manga and it is the kind of over-the-top Gothic melodrama that could easily be slipped into a collection by Edgar Allan Poe.
