Muramasa

In general, these two series do not share a similar asthetic. However, what they do share is the activation of abilities via perverted catalysts. In Muramasa, a sword's ability is activated if a perved deed is achieved. In Sekon no Qwaser, sucking breasts allows characters to bring forth their abilities.
