Finnel (フィンネル, Finneru?), full name Finnel_ax.Forged Clustania (フィンネル_ax.鋳種クラスタニア, Finnel_ax.tetsushu kurasutania?), is another main heroine and a really clumsy β-type Reyvateil who works in a restaurant known as Yokkora Bistro as the mascot girl, which is situated on the Eternus Shaft. Her clumsiness makes people nervous with her reckless actions. As unlikely as it may seem, Soma, the deadliest hitman hides deep within her. She follows Tatsumi around because her duty is to bring the Heart of Gaea to the soil of Clustania. She's a typical tsundere who hates the fact that she's so stubborn. She is also secretly a masochist.
She loves cold treats like ice cream and snow cones, but because she's always so careless, she always gets brain freeze.
Finnel's mind guardian is Momoko.
