Ayumi is a high class Angel. She is also the third oldest member of the group. And of course Ayumi is the turtle. She tends to have rivalry with Mika. As sort of a joke on that old story. The Tortiose and the Hare. Of course since the turtle won as it were the rabbit tends to be the one with the stupider ideals while the turtle Ayumi seems more level headed. Ayumi is definitely level headed over all. And she does like to plan ahead. However she does tend to bask in punishing Mika too much sometimes.
