The secret technique of the secret technique

I selected the technique "I tech" from 10000 of the total of the applicants received from the technique = "my skill" user. It is not an advanced technique for the AV, and it delivers it without leaving "Boku's secret skill instruction" which seems to have demonstrated the great effect by the practice of the user. It is an art that can only AV AV actor. This is the technique that ordinary civilians used in daily life and were actually effective.
