Thundering Roar: Muchōrin

Its abilities are the incarnation of matter. In the Teach Me, Miss Litchi segement in Continuum Shift, Luna mentions using it will cause her to lose memories. Whether this means temporary loss or complete amnesia is uncertain. Muchōrin means, very roughly, "Untolled Bell". Arma Reboare means, roughly, "Ringing Weapon" or "Resounding Weapon" in Latin.
