The tonberries only emerge under the cover of thick fog. Even if you search for them on a misty day, I suspect it might prove difficult for travelers from afar to spot such tiny creatures.
Of all the monsters that inhabit Orience, Rubrum researchers are perhaps least familiar with this reptilian creature, although a colony of tonberries is to reside in the northern reaches of Concordia. Commander Kurasame often travels with a companion bearing a striking resemblance to this monster, but his comrade's relationship to wild tonberries is unclear.
This creature wields a sizeable kitchen knife and dashes in close to stab its opponents. When its friends fall in combat, the tonberry channels their feelings of enmity toward their murderers into a devastating attack known as Everyone's Grudge. Despite their adorable appearance, tonberries are quite powerful and should be approached with caution.
