Hysteria Mode (Hysteria Savant Syndrome or HSS) is a trait which causes the bodies of those carrying it to activate 30 times more neural transmitters than the average person, which makes the function of his central nervous system, namely the cerebrum, cerebellum, and spinal cord, accelerate dramatically when he is sexually excited.
As a result, in Hysteria Mode, logical thinking, judgment and reflexes all rise exponentially. Users enter a temporary super mode, like a transformation. It is seen in the novel that Hysteria Mode also permits the user to develop a sixth sense.
Kinichi describes Hysteria Mode as the ability to "use a gun to its fullest potential".

Hysteria mode is activated through sexual stimulation.
- Hysteria Mode's most common trigger is coming in sexual contact with women
- Observing a woman that's dressed in rather exposing clothing can trigger it, albiet at a slower and more unreliable rate
- Kissing a woman instantly triggers Hysteria mode and has been noted to make the user even stronger
- Kinji noted when kissing Aria he feels a Hysteria mode that's exceptional compared to the rest, possibly implying if the user is in love with the trigger then the resulting HSS is exponetially stronger
- Hysteria mode can also be triggered through endulging in a fetish
- Kana can trigger his through cross dressing
- Tohyama Kinshirou was noted to grow stronger the less clothes he wore, indicating a stripping or nudist fetish
- Vlad's modified HSS is triggered by sadistic pleasure
- Porngraphy is also a probable trigger as Kinji tries to avoid looking at that material and the erotic games Riko sends him to pick up for her
- An exception to the sexual trigger is Sherlock's modified HSS, which is something he has developed and can trigger through his intense trainning
- The user develops a hyperprotective manner towards girls, protecting them, speaking seductively to them and never hurting them no matter what happens. (At least, in Hysteria Normale.)
- Hysteria Mode can also alter the attitude and personality of the user
- At its base, Hysteria mode increases the users mental, logical, and physical capabilities by 30
- Exclusive to Kana, his cross dressing trigger for HSS allows him to override the "harm no woman" restriction
- In a woman's case, the user acts in a way to maniupulate the men around her
- It should be noted that the physical boost they recieve from HSS is weaker compared to that of a male's
- It should also be noted a female user can harm other women but cannot harm men
Despite the massive power and potential Hysteria Savant Syndrome has, it does have quite a few devestating flaws to it
- Males under HSS cannot direcly harm a woman, even if she is attacking him. Though the man can evade and defend himself, he cannot keep it up forever. Kinji experienced this first hand against the Cao Triplets, which almost cost him his life
- Conversly, Kaname, the only known female HSS user, cannot harm a man
- Though subjective, HSS drastically alters the personality of the user and the user will remember every second of it. In Kinji's case, he becomes a "terrifying gigolo" which embarrasses him to no end.
- Hysteria mode can only last a few minutes at a time, although the exteremity of the trigger (such as kissing a woman opposed to her flashing the user) can make HSS last longer.
- Younger HSS carriers are more sensitive to triggering, in Kinji's case it left him scarred and developed a hatred for women due to them exploiting it
- "Unrefined" triggers for HSS often have nasty side effects. In Kana's case, he can remain in HSS the entire day but afterwards falls into a coma for up to 10 days due to the tremendos stress HSS places on his brain and nervous system
HSS--Hysteria Mode, because of maturity, or times of need, it will evolve and form a derivative.
- Hysteria Normale (Hysteria Mode): It's the normal Hysteria Mode, logical thinking, judgment and reflexes rise exponentially.
- Hysteria Agonizante (Near-Death Hysteria Mode): Those men that receive near-fatal wounds, will, before they die, feel an enormous instinct to leave their young behind, this is the Hysteria Mode under the influence of that instinct.
- Hysteria Berserk (1.7x Hysteria Normale combat ability at the cost of some of the logical thinking and judgments that regular hysteria mode gives): This Hysteria Mode is fueled by jealousy, triggered when the user sees a woman being taken away from him by another man. Hysteria Berserk accelerates, aggravates, and enhances the hate and jealousy that the user feels for other men, and is thus, is a very dangerous version of Hysteria Mode. Sometimes, the hatred and jealousy the user feels may spill over to women as well, allowing men in this version of Hysteria mode to harm women. In return for this, the user's battle prowess is increased to 1.7 times that of Hysteria Normale, but his thoughts will be completely focused upon aggression, so this too, is a double-edged sword. Though Hysteria Beserk will appear in unpredictable situations, it is not impossible to control. However, the first time is always difficult.
- Meza Hysteria (1/10 power of Hysteria Normale): If activates when you're starting of been aroused but something happens before entering Hysteria Normale and it stops in Meza Hysteria, while for a short amount of time the abilities increases only by a little.
- Dream Hysteria (Hysteria Normale) is the Hysteria Mode triggered when sleeping. It sometimes does nothing to do with the reality but, the user can wake up in Meza Hysteria.
- King Hysteria (1.2x Hysteria Nomale) This state of Hysteria Mode is triggered when multiple close female associate of Tohyama man is being attacked by an external threat , this is evident in chapter 11 of the light novel where Kinji was force to enter this mode by attacks of G III . The calculation of the battle prowness is directly proportionate to the number of female the man wants to protect , eg 1.2^5 when there are 5 women being attacked.
Feats Performed in Hysteria ModeEdit
- Accurately aiming and firing bullets into the barrel of the enemies' guns, effectively rendering them useless. (First used in the Segway Chase in Volume 1)
- Cutting a bullet in half with a knife. (First shown at the end of Volume 1 in the fight against the Butei Killer).
- Performing sword edge-catching using only two fingers. (First shown in the fight against Durandal in Volume 2)
- Shooting and hitting other bullets using the user's own bullets-- 'Billiard Shot'. (First shown in Volume 3 in the fight against Vlad)
- Derivative of 'Billiard Shot'. Bounces the enemy bullet back into its barrel, then uses the 2nd bullet of his burst fire to -- 'Mirror Shot'. (First demonstrated in Volume 4 against Kinichi/Kana)
- Catching a bullet fired at the user using his teeth. (Shown in Volume 4 during the fight against Patra)
- Kinichi/Kana's 'Invisible Bullet' can only be used in Hysteria Mode.
- 'Ouka' - 'Cherry Blossom', By utilizing the incredibly fast reflexes imparted to him, the user is, for a moment, able to swing a bladed weapon at 1236 km/h, which is faster than the speed of sound. However, the attack is a double edged sword, as it causes massive damage to user. However, the attack itself is unavoidable, and cannot be dodged by any means. However, it can be defended against in other ways, such as through use of Edge-Catching. Only usable under HSS, due to the need for the enhanced reflexes that it imparts to the user. (First used in Volume 5 against Sherlock)
- Following the acquisition of Desert Eagle and Scramasax, Kinji can now dual wield his weapons when in Hysteria Mode, rendering him as the third known Quadra in the series. (First shown in the decisive battle against Cao Cao triplets in Volume 7)
- Slash, a derivative of sword edge catching. Using four fingers (both left and right forefingers and middle fingers, respectively), Kinji performs edge-catching in right hand on a bullet. However, unlike a blade, it is not possible to catch a bullet using edge-catching due to velocity and its small size-- all it does is divert the flight path slightly. Following up another edge-catching in the left hand, the slash technique is completed. As a result, he can successfully parry a bullet by diverting its trajectory diagonally using fingers. Kinji named the skill after the symbol "/", by the manner of how the bullet was deflected. (First shown in the decisive battle against Cao Cao triplets in Volume 7)
- Kinichi is shown to be able to consistently swing his scythe at supersonic speeds. (Shown at the Volume 4 by Kinichi/Kana at the overwhelming fight with Patra)
- It appears that the Tohyama's, the main carrier of the gene, are leaders of justice, strength and law as Kinji describes that his family has worked the guardian jobs for generations.
- Interestingly, Tohyama Kinji had developed another, personal derivative of Hysteria Mode he dubs as "Hysteria Wiseman Mode". This mode allows him to remain unaroused for a fair enough length of time. However, this method of protection for him is imperfect. He cannot maintain this mode for very long if the sexual arousal level in the room he is currently in keeps increasing. (This mode only makes an appearance in the Blu-Ray Side Stories and is therefore not applicable to the actual series.)
- Based of the real medical condition savant syndrome
- Despite being closely associated with sexual excietment, the common anime trope of nosebleeds has never occured possibly due to how HSS modified the body
