Eba's pendulum

Many different mamono exist in this world as of today, but even amongst them [Alps] have an extremely peculiar nature.
 As for these mamono that are given birth when a human male mutates into a female mamono via becoming an incubus first, I will not write down a detailed explanation regarding this monsterisation here, however for the circumstances to happen were a male incubus turns into a female to happen, the most important thing is the [disposition]. There are 2 points, one must either hold the wish  [to become a woman] in the innermost depths of their heart, or must strongly give their hearts to [a person they want to be with], which means there being a male they yearn for.

However, despite holding such wishes, most Incubi have a masculine spirit, so cases were they monsterise into an Alp after being both aware and embracing these desires are extremely rare. Also, if it should be seen as forbidden love, then coming to accept such an immoral wish is extremely difficult and accompanied by unbearable agony.
 Hence, while there are many in this world with the disposition to turn into Alps, their suffering continues, as there are by no means few men swayed by unapproved feelings towards their loved one.
 To help the kindred souls in such pain, and to fulfil much more love, Lescatie's dark strategist and Alp Eba has developed a truly magnificent magic tool, this very pendulum!
 Embedded with Eba's unique magical powers as an Alp, it will only react to those who posses the same disposition as Alps, and will indicate them!

The magic powers the pendulum is charged with will adhere to males that have been indicated by it, making it known to the surrounding mamono that this man holds the disposition to Alp... Namely, mamono will no longer perceive and treat this man as a male, but as a [female]. And so they will rush down on him, not to turn him into their husband, but in order to turn him into a mamono!

Usually, no matter how much he secretly desires it from the bottom of his heart, it is normal to be opposed things like becoming a mamono, or having to let go of the fact that he is male. But for a man with the disposition of an Alp, the magic power of this pendulum will calm down his spirit, letting him accept things like being attacked by mamono, and that he will turn into an Alp upon monsterisation.
 The magic powers of the pendulum will urge self-awareness to see himself as a [female], and the thought of him being corrupted into an Alp will turn into something giving him otherworldly strong intoxicating pleasure, so in other words with this his transformation into a mere female can progress more smoothly...!
 But of course this is not all! In case a male human holds this pendulum, then the pendulum will react to [males] with strong affection towards the user of the pendulum, or in other words those with the disposition of an Alp!

This pendulum will show the right way to those destined to become [Alps], since this wonderful magic item is able to certainly guide them into alping, and in practice with this magic item a by no means negligible number of Alps may be born in Lescatie, leading  new lives as females!
 As long as one has this, all the alp candidates that still live in this world have nothing to be worried about! As I wrote earlier, Eba who has not forgotten the pain of falling in love with the man in one's heart before turning into a mamono, has developed this magic item with the intend of releasing other Alps of this pain, if even only a little bit earlier.

As immature as I am now, looking at this magic item, the desire to one day create something for the sake of those with similar intentions grows hot in me...!
