Yobutaro is a mage who is also skilled in using a spear, which is why his weapon is a spear-staff hybrid. He travels the world, looking for ways to utilise the resurrection art 'Shin Megami Tensei'...
Yobutaro's weapon is a staff with a spear head. Above the white shaft of the staff is a hollow green circle with a hollow five-pointed yellow star inside it, each corner the same distance apart and touching the inside of the circle. The silver spear head is suspended five centremetres from the top of the circle with a smaller brown shaft. Two smaller silver triangles that hang from the bottom sides of the circle from an equilateral triangle along with the spear head.
The spear-staff allows Yobutaro to perform magic to a high degree as well as summon powerful creatures.
