Tail Braclet

Tail Gear is bracelet devices invented by Thouars. Tail Gear is an armour that transforms the users into Twintails warrior girls and it is triggered by the user saying "Tail On!".

To make the user compatible with the armour it must change some of their physical attributes to fit. This is why you can see some of the Tail Gear Users human forms when they transform.

The "Red Courage" Tail Gear
The Red Courage Tail Gear is the Tail Gear that holds Tail Red it was passed down through generations of women and is currently used by Sōji Mitsuka It allows its user to transform into the young Twin Tail warrior girl Tail Red. It is by far the Tail Gear that causes the largest difference in appearance to be compatible changing Soji's gender and age because the Armour was built for a young girl.

With the Tail Gear Tail Red can use the Ribbons on her head to summon weapons such has her signature weapon the Blazer blade a long red sword that can send even the heaviest opponents flying.

Like all the other Tail Gear's it features this Tail Gears version of the Aura Pillar when all the gem's on Tail Red's armor glow she fires a giant red energy beam from her cuff's that homes in on her opponent like all the other Twin Tail warriors Tail Red can only activate it when she is distressed.

The "Blue Love" Tail Gear
The "Blue Love" Tail Gear was the second Tail Gear to appear when Tail Red wasnt strong enough to tackle and enemy on her own it is currently used by Aika Tsube and previously used by Thouars to transform into Mighty Tail Blue.

The armour is mostly made up of a Light Blue colour and because the armour was built for Thouars it is was very revealing and designed for Thouars bigger breasts and not Aika's flat chest.

It transforms Aika into the Fierce Twin Tail Girl Tail Blue it doesn't have a drastic effect on Aika's appearance to make her compatible only giving her Blue hair and Blue eyes but has a massive effect on her physical abilities.

The "Yellow Hope" Tail Gear
The "Yellow Hope" Tail Gear was the Third Tail Gear and was made when Aika wasn't happy with her Tail Blue form not expanding her breasts. It wouldnt work when she tried to use it as she had grown into her Tail Blue form so much that inside she was rejecting it.

When Soji discovered Erina Shindō had a love for Twin Tails so strong she could see his Tail Gear and knew he was Tail Red he gave her the Yellow Hope Tail Gear And she successfully transformed into the big breasted, big butted, Tail Yellow.
