All katon element ninjutsu,
Name: Magen: Jigoku Gouka no Jutsu - Demonic Illusion: Hell Fire Technique
Type: Genjutsu - visual
Rank: B
Requirements: None
Description: This illusion makes the target believe that a huge fireball is falling from the sky. After it hits, the area is engulfed in intense flames and the target will feel like they're burning if they were unable to get away in time. This genjutsu can be used against a large number of opponents at the same time, but it is rather easy to overcome due to being rather basic

Name: Magen: Jubaku Satsu - Demonic Illusion: Tree Binding Death
Type: Genjutsu - visual
Rank: A
Requirements: None
Description: After the user forms the necessary hand seals, their target will believe a large tree appeared behind them and that large branches have wrapped around their body, restricting their movement. The user will then approach the target, which will seem like they appeared from the same or another tree to the victim, and attack the captured opponent. While this is an illusion, the attack itself is real, since it mimics inside the illusion what is happening in reality. Chakra-based attacks cannot be used while this genjutsu is active.

Name: Magen: Kasegui no Jutsu - Demonic Illusion: Shackling Stakes
Type: Genjutsu - visual
Rank: A
Requirements: None
Description: A rather simple illusion, it will make the target believe that they were pierced by several large stakes, which nailed them to the ground. While it is quite painful, it does not bind the target completely, meaning they may still be capable of movement, though they can't change their location until the genjutsu is released or dispelled.

Name: Magen: Kyouten Chiten - Demonic Illusion: Mirror Heaven and Earth Change
Type: Genjutsu - other
Rank: S
Requirements: Genjutsu Specialist
Description: A very strong genjutsu technique that can only be performed by a true master of the art, it completely reverses a genjutsu that the user fell victim to onto the enemy who used it. While incredibly powerful, this technique's downside is that the user may not have the opportunity to form the necessary hand seals after they're caught in an illusion.

Name: Magen: Narakumi no Jutsu - Demonic Illusion: Hell Viewing Technique
Type: Genjutsu - visual
Rank: C
Requirements: None
Description: This genjutsu plays on the target's hidden or not so much fears. As such, it can differ greatly in particular effects, from showing them an important person in a dying state if that's what they fear, to making them think like they're standing on a small platform over an abyss if they are afraid of heights, to making them think there are hundreds of mice running around if they are afraid of the little animals. However, this technique is rather easy to defeat since it is quite obvious and will disperse if the target confronts the particular fear the illusion is played upon.

Name: Mateki: Mugen Onsa - Demon Flute: Illusion Tune Chains
Type: Genjutsu - aural
Rank: B
Requirements: A musical instrument
Description: This genjutsu does not require any hand seals, but instead takes some skill playing a musical instrument of some sort to produce sound waves. Upon hearing the tune, the target will find themselves in a strange place filled with red sand, with their limbs bound by strings that hang from the sky. They will then think that their flesh is melting off their bones, which is frightening and painful.
and this speical ability
Name: Jujutsu: Shijihyouketsu - Sorcery: Death Controller Possessing Blood
Requirements: Must be trained as a 8-point Kinjutsu
Special Ability Points: Maximum Amount of Points at any Given Rank
Description: A unique ability that goes along with a small religion praising the evil god Jashin. It has two effects: it makes the user practically immortal and the actual technique. The immortality part allows the user to survive any injury with no noticable effects on their performance. Even having their head cut off will not kill them, however, highly advanced medical ninjutsu or another ability with similar effects will be necessary to reattach the head and restore control over the body, and severe damage to the brain will probably be fatal. It is not known for sure, but believed that those who have this ability age normally.
The technique requires some preparations, which consist of two parts. One is tasting the enemy's blood - even one drop is enough - and the other is drawing a circle with an inscribed triangle in it on the ground, through whatever means. Once the preparations are completed, the user must step into the circle and trigger the technique. Their skin will turn black and there will be white lines on it, as if projections of their bones. From that point on, every injury they receive while inside the circle will be transfered fully to the one whose blood they tasted. This technique can only target one person at a time, any new blood the user tastes "overwrites" the previous sample. The blood sample "wears off" after six hours.
Although insanely powerful, this technique has a downside. The specific contract they sign with their god, which allows the immortality and injury transfer, makes them unable to use any chakra-based techniques beside the basics and bloodline of C-rank or below, if any. They must also spend a lot of time praying and performing rituals, so their skills may degrade (you lose one secondary fighting style or, if you had none, your specialization downgrades to a primary style).
