Densenken is able to effectively counter the Umisenken. The opening move of the Umisenken is a mental effort by the probing user. In effect the techniques of the Umisenken and the Densenken are similar in that they manipulate static/active bioelectrical patterns. But Densenken practitioner’s generate so much electrical energy that essentially negates the Umisenken. This is also able to negate a warriors sixth sense. The Umisenken and Sixth sense are in effect low level telepathy technique so only the most powerful telepath's stands a chance of breaking through.
