Boosted Gear

**Boosted Gear**, also known as the **Red Dragon Emperor's Gauntlet** is a Sacred Gear used by Issei Hyoudou before. Listed as one of the original thirteen Longinus, specifically a mid-tier Longinus, it has the spirit of the Welsh Dragon, Ddraig, residing within it.

## Summary

In the past, **Ddraig** fought against his arch-rival, the Vanishing Dragon, Albion, in a battle that was interrupted by the Angels, Devils, and Fallen Angels who were at war during the time. In anger, both Dragons attacked the leaders of the Three Factions, which led to their bodies being destroyed and their souls being sealed into two separate Sacred Gears, with Ddraig moving into the "Boosted Gear", a Sacred Gear that eventually became one of the eighteen varieties of Longinus.

In the present day, Boosted Gear's owner is Issei Hyoudou but he was later killed by Tenraku Yamazaki (a reincarnated person) and the Boosted Gear was also taken by Tenraku. Later in the battle with Yuuya, Tenraku was killed by Yuuya, resulting in the Boosted Gear becoming derelict and Ddraig decided to choose him as the next owner.

Due to Yuuya's modifications, the Boosted Gear can appear and be used by multiple people at the same time as long as Ddraig agrees. That's why Rias and many other women have Boosted Gear.

## Appearance

**Boosted Gear** takes the appearance of a red gauntlet with a green jewel and 2 golden spikes that manifests on the user's arm. In the anime, its initial state looks like a regular Twice Critical. After a certain time, it transforms into a more Dragon-like gauntlet that covers up the user's hand and a majority of the arm. When the Boosted Gear reaches its second liberation, it gains another green jewel and a total of 10 golden spikes, aside from covering more of the user's arm.

## Abilities

Boosted Gear is a red gauntlet housing Ddraig, the Red Dragon Emperor, which allows the user to double their powers every ten seconds without limit until the user reaches their limit, whether it's their physical abilities, magic or demonic power based on the user. It has been described as allowing the wielder to surpass the powers of God and Four Great Satans for a temporary amount of time.

In response to their user's feelings, the Boosted Gear can transform into its final state, letting the user to transfer their increased power to other people or items, increasing their capabilities. The transferred power can even be performed on multiple targets at the same time, however, about 70 to 80 percent of the boosted power will be transferred. Boosted Gear can also determine the opponent's power level and inform whenever his boosted power reaches a sufficient enough level to defeat an opponent.

## Weaknesses

With Ddraig sealed within Boosted Gear, its possessors becomes vulnerable to the same weaknesses common to Dragons, such as Dragon Slaying magic, swords, and curses, as if they were Dragons themselves.

Also continuous use of Boosted Gear's doubling abilities will continue to drain the user's stamina, burdening their body far more than other Sacred Gears. If the user reaches their limit, the Boosted Gear would enter its **Burst** state, signifying their limit, where the user will or have exceeded their physical limit.
