Tap

Tap is a President of Hell and one of its Princes. He commands four of the Kings of Hell. He serves Byleth. He rules the demons who serve Amaymon, and commands sixty legions.de Plancy, J. C., (1863). Dictionnaire Infernal. 6ed. pg.651 
De Plancy occasionally refers to Tap and Gaap individually even within the same sentence, as well as also referring to one or the other separately, which could mean that this demon has multiple aspects with individual identities, personalities, and abilities. 
== History ==
A group of necromancers summoned him, offering him libations and mass slaughter, in accordance to instructions they believed to be from Solomon, but were actually from Cham, Son of Noah. 
To honour Byleth, he composed a work of art and a book on mathematics. 
== Appearance ==
He takes the form of a man.
== Summoning ==
The summoning of Tap has the following prerequisite:
* He must be summoned at noon.
Instructions for summoning him as Gaap are supposedly found in a book quoted by the prophets Elijah and Elisha, and require the names of God mentioned in the Keys of Solomon. 
If the art created by Tap for Byleth is known to the summoner, then both Tap and Gaap will be compelled to obey the summoner.
== Knowledge ==
Tap and Gaap can teach his summoner the following:
* How to get people to fall in love with them
* How to cause people to hate them
== Other Abilities ==
He can quickly transport his summoner (and others) to other locations of their choice.
