Euphoria

is a simple Genjutsu, but quite difficult to learn. Though when one possesses it in his arsenal, it becomes incredibly effective.

User
By simply snapping their finger, the user induces a genjutsu to the target(s), whereby they feel quite happier and see an action they desire happen, although it did not, Similarly to the Demonic Illusion: False Surroundings Technique. Though this technique is cast by affecting the hearing of the target through snapping hands, their eyes are also affected, and this makes it difficult for lesser trained dōjutsu users to detect it, with the exception of the Byakugan. Since this is cast through hearing, those possessing the Rinnegan are not immune to its effects, and this might be fatal. Non-sensor shinobi may fail to notice this as they are pre-occupied with their own happiness and fulfilling their own ego. Furthermore, the traditional method of releasing chakra does not work, similarly to its sister technique; Ephemeral.

Drawbacks
The only drawback is that one must be atleast 5m close to the opponent in order for the target to hear the snap of fingers, though this weakness is removed by exerting chakra to your fingers and making the snap quite louder.
