Transforming into their respective Senshi form
Is the Genius Girl a Youma? Brainwashing School of Terror (Mercury)
In the manga, the first time Ami received her pen, she actually was seen using it for writing before using it for transformation. The Sailor Senshi sacrificed their pens, in order to awaken Sailor Moon, who was within Metallia at the time. These pens were eventually replaced by the Star Power Sticks.
- In the anime, all the Inner Senshi had identical transformation pens (except for the color and sign), but in the manga Sailor Venus had a different pen that came from her Sailor V times.
