Angie is a very spiritual person, believing that Atua, the god of her island, is always at her side. She has a pious heart and likes praying, having a very strong faith in her god, and she is very willing to help and assist other people with spiritual matters. She often searches for things to offer as blood sacrifices and somewhat creepily talks about her need for blood and asks other students to offer her some. She also has a habit of speaking on behalf of her god and strangely these words can sometimes turn out to be very truthful. As another eccentric habit, she freely uses her own original Japanese, like "Bye-yonara" or "strange miracle", which shows a little bit of her artistic side. Similar to Ibuki Mioda, she also calls everyone by their first names in the Japanese version, which is considered eccentric since Japanese acquaintances normally refer to each other with their last names instead of their first names. However, in Angie's case, this seems to be because she's not a Japan-native.

It should be noted that while she is very manipulative and selfish, Angie does not appear to be intentionally malicious, and she often genuinely wants to encourage and guide others through her words. She plans to make the academy environment "heaven on earth" so that people wouldn't have the will to escape and start the Killing Game.
