Sachio Sawada

Sachio Sawada (沢田 さちお) is a street calligrapher and poet who uses the Liar Memory to become the Liar Dopant (ライアー・ドーパント), referred to in urban legends as the Radio Tower Clown (電波塔の道化師). Armed with the Lie Speaks (ライスピークス), a staff with a large speaker in a shape of a giant mouth, the Liar Dopant's signature move is converting any lie he says into his Lie Needles (ライニードル), forcing whoever it hits to fall under the Dopant's deception. Though he is paid by Yukiho to help Jimmy win the Fuuuuuutic Idol (フーティックアイドル) competition, he turns on her after she fails to pay him his ideal amount, revealing the ruse in front of Jimmy. Once his cover is blown, and his being a fan of Wakana Sonozaki's radio show used against him, the Liar Dopant is defeated through the combined powers of Kamen Riders Double and Accel, with Double dealing the final blow using CycloneJoker's Joker Extreme.

In the music video for "Love♡Wars", the Liar Dopant makes a cameo as he fights the Kamen Riders.
