Travelling, The Way of Curry
Marceline F. Mercury
Ringo Akagi (赤城林檎) , real name Marceline F. Mercury and also known as Zwei, is a character introduced in XBlaze Code: Embryo. Ringo is Touya Kagari's senior at Maha Raja. In truth, she is actually one of the Ten Sages who left Ishana to travel the world learning about curry.
A tall and curvy woman with long pink and red hair, light blue eyes, and fair skin. This hair is usually wrapped into a messy bun with two golden ropes while Ringo is working at Maha Raja, but she lets it down when assuming her identity as Zwei, also letting both ropes dangle freely. Ringo is usually seen in a white shirt with most of its tops buttons undone, revealing her cleavage. Over her chest are black cloths that also wrap around her thighs and arms. Ringo also wears a short light blue skirt and bangles of a similar color. Her main look is completed with black and pink platform shoes. When at Maha Raja, Ringo wears a black apron over her main attire.
When at the swimming pool, Ringo wore a tight black two-piece bikini. The top piece had three blue triangles and the bottom piece had one. She also wore a pair of matching black bands and a black choker. She had a small white jacket on top.
Ringo is eccentric and completely obsessed with curry. After trying it just once she left Ishana and dedicated her life to learning about curry. She will ramble on about curry to her junior Touya. Additionally, she has developed a strange opinion on "curry mannerisms," judging a man's enjoyment and etiquette based simply on the state he left his plate in. Ringo also likes to tease Touya about the girls in his life. However, Ringo has a hidden serious side. She believes that life is all about learning things for oneself and hates things like TOi that take the work out of it.

- It is never outright stated that Ringo is related to Nine the Phantom and Celica A. Mercury. However, given Ringo's similar appearance to Nine, that they share the same last name, are from Ishana, and the ability to use sorcery is genetic, they are likely related.
- In Lost: Memories, Ringo wears a brown paper bag over her head with one hole open for her eye. This is a reference to Faust from Guilty Gear, another one of ASW's properties and the spiritual predecessor to BlazBlue.
