Since the three last male witches is one of the mysteries in the story that need to be solved. I'm putting some infos and theories here.

Infos:

• Takuma can identify all the witches in his group and who their powers were used on.

• So far, only Kurosaki uses his power through kissing.

• Ichijo's power is considerably negative, filling victim's thought with jealousy instead of affection or just temporal submission. Compare to Odagiri and Tsubasa, the control is not direct control over the victims.

• Yuri's power in one-way power, unlike Otsuka or Kotori.

Theories:

• Witch Powers are based on the witch desire. You need really strong desire to become a witch. (Like in Umineko)

• If your desire are somewhat selfish, you will get moderate power with drawback. If it is good, you get stronger power with less drawback. However, if your desire is malicious, you get "evil" and strong power with some drawback (Ichijo's power effect varies and cannot control them directly, Yuri can control one person at time).

• The reason that most male witches don't use kissing is because "men aren't good at/supposed to display their affection" since kissing is the most direct way of displaying affection (Takuma's "test" with Yamada and Shiraishi kinda supports this). Also, the reason that there haven't been (or for sometimes) male witches because "women are wiser with power".

• Which is why only Kurosaki uses kissing: he is capable of love/affection. Ichijo is mostly into jealousy and evil ambition. While Yuri is not explictly comfirmed, seeing the once happy Himekawa being alone again might rises some degrees in hatred/revenge department.

• The three male witches must have kanji/radical for number 4,5, or 6 in their names/surnames like Kurosaki(2), Ichijo(1), Yuri(3), and Takuma(7).

• Due to the number theme, Hagewara(He has "6" in "Mut"ta) becomes prime suspect for becoming a witch in the future if his desire is strong enough.

Speculation:

• Body Swapping Male Witch:

** Required desire: dissatisfaction with self (confirmed)

** Moderate: Simple swapping

** Good: Swapping body and emotion (for further successful swapping)

** Evil: Simple swapping without kissing with control over both self and switched body.

• Premotion Male Witch:

** Required desire: wish to know the future

** Moderate: Future cannot be changed

** Good: Future can be changed

** Evil: Can predict future that the user desires that will come true without kissing

• Invisibility Male Witch:

** Required desire: doesn't want to be seen

** Moderate: Trick brain into forgetting the user

** Good: Become invisible

** Evil: Make people disappear without kissing

Any opinion?
