Bermuda Triangle Emblem

The Bermuda Triangle, written as Bermuda △ in Japanese version and Korean version (バミューダトライアングル Bamyūda Toraianguru), is a clan from the nation of Magallanica that consists of mermaid pop idols. Bermuda Triangle was also the first clan given an extra booster set that was completely centered around them, and are unique in that nearly all of their cards are released in Extra and Clan Booster Sets. In the lore, this clan is generally left alone during times of war and strife, and thus spend their time on becoming famous pop idols for the world to enjoy. In the events of the Cardfight!! Vanguard G series, the student council president has become popular due to her voice apparently having the power to summon deities from the heavens, as well as other entities.


The clan's playstyle revolves primarily around returning your units from the field to the hand in order to re-assemble your field or gain effects, similar to how many vocal groups and choirs utilize different vocal ranges for their sounds. Most effects related to returning these units to hand involves gaining additional power and drawing more cards. A good reason for re-assembling columns would be having them become in "Harmony" to gain even more effects and power from each other. They also often have effects that call cards from the hand to open RG spaces, synergyzing with the return to hand effects to gain extra attacks.

Each archetype is centered around a certain troop or idol, with varying effects. The PR♥ISMs are the musical troop that follows the core mechanics of Bermuda Triangle the most. They bounce their own members to gain a lot of power while also superior calling them from the hand for more power or attacks.

Lauris is the president of the idol school "Triangle Academy", and has the greatest focus on the "Harmony" keyword.

The Duo troop can be seen as having a focus on solos, as their effects are name-based, requiring multiple copies of the same card in order to activate their effects.

Pacifica is an idol that powers up based on having multiple versions of herself in your hand.

Riviere is an idol Ride Chain that focuses on giving her supporters power while also drawing when successfully completing the chain.

Coral is another idol ride chain that focuses on putting cards into the soul to increase the G units' effects.

Raindear is an idol that has a focus on the trigger zone. More specifically, trigger checking other "Raindear" cards, as well as her supporters, in order to gain more drive checks.

The Chouchou troop has a different approach, where instead of powering up based on returning cards to the hand, they power up by returning them to the bottom of the deck instead.


What is Bermuda Triangle

"Bermuda Triangle" is the globally popular mermaid idol group which is active in the deep seas of marine nation "Magallanica". Their skills of singing and charming magic are their selling point, and it is difficult to obtain their sea surface lives' tickets. It is said that the days their lives are globally broadcast are "days where no bullets are shot in any place of the world".

"Triangle Academy", the Idols' Gateway to Success (Monthly Bushiroad July 2015)

"Triangle Academy", the Idols' Gateway to Success, is an academic institute established for the purpose of cultivating top idols of the next generation, and only chosen girls who have finished their cadet period are permitted to enter the academy. It is said that this academy holds two secret treasures left by the founders. "Twinkle Powder", the mysterious powder which could grant "legs" to mermaids by sprinkling over their tails. "Prism Pearl", the magical pearls that allows mermaids to produce their "voices" on land. The two secret treasures are granted to the teams who win "School Etoile Festa (a.k.a. SEF)", the annual live event in the academy. In addition, the winning team can go to a foreign nation they choose (limited to friendly nations) and perform live events in that nation. Because the nations would send top-level security teams which all members possess strength equal to those of knightly orders' masters, no harm would be dealt to the idols even if they are involved in troubles. Some treat this opportunity as stepping stones to raise their popularities, some treat this opportunity as mere chances to travel to nations they wish to go---this is varied. Nevertheless, it is no mistake that winning in SEF is the first and biggest target of the academy's idols.

What is the "Wedding Project"? (Monthly Bushiroad July 2016)
