Her full name is Tendou Alice.
A character from Blue Archive. Member of the Game Development Club.
Her name is not Aris. This is a misspelling of her name by a translator similar to the misspelling of Final Fantasy 7's Aeris (which was corrected to the proper name of Aerith) but unlike FF7's error, her name was misspelled intentionally to cause both outrage and censorship of the game because of her age.
The name 'ALICE' appears on her weapon and is the official name given to her in the original version of the game. It is also the generally accepted name by the game's fanbase which have made numerous requests to the developers to fix.
