Deep within the heart of the Muhammadiyah University of Jakarta, Meutya Budiyanto, Professor of Mathematics, sat amidst a room of computers. The sequences and theorems that passed by her eyes were always a step behind her own internal calculations. She scanned dates and names, population density and demographic forecasts. All of the data led to a single conclusion.

Indonesia was destined for trouble.

The terrorist activities of Marauding Tide, the suspicious peace of Singapore and the spreading insidiousness of the various Japanese ninja clans threatened Indonesia, and no one seemed capable of standing in its way. The West was satisfied that the threats were too distant from their own shores, and the East was more concerned with its own situation to care about over-arching ones.

Budiyanto closed her eyes.

Her faith and her knowledge convinced her that she was able to stand up for what was right and just, but she knew she could never act alone. Her intellect was formidable but she needed more. She needed other women to share her dreams, to fully represent the people of Indonesia. If she acted alone she would be classed as a Muslim hero, and ostracise those of other faiths. She realised that she needed to form a team of heroes from different faiths, as religion was a single force able to bring people together, as well as tear them apart.

She began to search for suitable partners, quickly locating Matahari Merah in Bali. The Balinese Hindu was not interested in protecting the wider country, having found herself a stable life in her home city. Budiyanto didn't give up, but turned her attention to Kurus, a Christian businesswoman from Jakarta, who joined willingly and with such an openness that Budiyanto felt vindicated in her dream. She wasn't mad. Others felt the same way as she did.

After the Bali Bombings, Budiyanto approached Matahari Merah again and in the woman's grief and shock, Budiyanto found her third Angel.

Budiyanto possesses an incredibly complicated brain, and has been classed as a mathematical ubergenius. She is a teacher as well as a perpetual student, keen to learn more information and to compare and contrast it to her existing database. As the leader of Bidadari she is the most patriotic and idealistic of the three angels, caring for her fractured country and its population more so than the fructuous government. While not believing she is above the law, she certainly has little respect for it.

“I am constantly surprised at your level of ignorance.”

Matematika, which means mathematics in Bahasa, possesses an uber-enhanced brain and is able to perform incredible feats that are far beyond the normal human. She is one of the most intelligent women on the planet, and is an expert in a variety of sciences and knowledge, particularly in mathematics and the manipulation and programming of computers.

Matematika wears a deep purple abaya and hajib which serves to identify her as a Muslim as well as help to conceal her identity. Matematika is determined to present a heroic figure of Islam to the world, especially in light of the terrorist activities of Marauding Tide and Fatwa. Her clothing is armoured, providing her with protection from conventional weaponry. Out of uniform, Budiyanto wears casual clothing depending on the circumstances. When she is teaching she often wears a suit with trousers.
