Reika is the stealthiest member of The Lost Ones resistance and this is why she is known as The Widow. Reika and Wendy are the only ones skilled enough to infiltrate enemy organizations as spies without getting caught, as Griffon and Vox would often start trouble and disrupt the mission. Reika is also the engineer of the resistance, able to craft weapons and technology they can use in their fight against the empire. She is an extremely skilled assassin as well as sniper who can keep calm in the most terrifying situations. It is only later that we find out she is from the same town as Roy and she actually helped him when they were younger.
