Lumi is extremely shy and not fond of people really, she doesn’t trust them. She prefers to be alone, but likes her older siblings as well because they make her feel safe. A lot of the time sh feels scared when she meets new people, fearing they'd try to hurt her.
She’s very sensitive and upsets easily. She wishes she were as cool and tough as her brother and sister, but she just isn’t. She often gives up too easily because she doesn’t think she’s strong enough to do things, but she doesn’t realize she’s stronger and braver than she actually thinks she is and if she just had faith in herself she'd be able to do things.
She’s extremely quiet and quite sneaky, sometimes she can be in a room and people have no idea she’s even there. Of course, a lot of the time she behaves politely like a normal cute little girl, but she's attracted to secrets and enjoys sneaking around and finding things out that she maybe shouldn't. She can also use her charm, cuteness and innocent reputation to get away with things easily though, nobody believes she would ever do anything wrong.
Cristi and Eca are her big brother and sister. She loves them both very much and feels safe when she's with them, she isn't sure what she'd have done if they'd been killed as well. She knows they'd both protect her if anyone tried to hurt her and she likes to have a laugh with them as well.
The rest of Lumi's family were killed by a muggle gang when she was only four. She hates to think about this though and never mentions it to anyone, but she'll never forget it. She, and her siblings, survived by hiding and so that's what she always does when she's scared, because it worked in the past.
Emelia Dalca was introduced to her by her big brother and sister. At first Lumi was very afraid of her, but her siblings helped her see that Emelia wouldn't hurt her, so she feels a little more comfortable around her now.
At the same time she also met Alfred Caison who seems quite nice and funny, so she quickly discovered he was nothing to fear.
