Tom Clancy's Rainbow Six Siege - Echo Operator

Tom Clancy's Rainbow Six Siege - Echo Operator

Masaru Enatsu (Japanese: 江夏 優[3], Enatsu Masaru), codenamed Echo, is a Defending Operator featured in Tom Clancy's Rainbow Six Siege, introduced in the Operation Red Crow expansion alongside Hibana.[4]


Masaru Enatsu grew up in Suginami City, Tokyo. This heavily populated city center is home to several animation studios and technology companies. At 16 years old, Enatsu was already challenging the robotics field by creating autonomous flying robots capable of search-and-rescue missions in highly difficult conditions. Two years later, he won the International Aerial Robotics Competition (IARC) and is known as having pushed the limits of what flying robots could accomplish.

Enatsu was noticed by the National Police Security Bureau during his studies in Science and Engineering at the Tokyo Metropolitan University. Enticed to test his devices on the field, he entered the National Police Academy. A year later, he joined the Tokyo Metropolitan, Police Department Special Unit.

Efficiency-obsessed and blunt, Enatsu is a talented officer despite his apathetic nature. In the wake of Nagoya's hostage crisis in 2007, Enatsu decided to transfer to the Aichi Prefectural Police Department Special Unit.[5]

Psychological Profile

Singularly focused, Enatsu's blunt communication style divides group harmony. His tendency to dismiss feedback has kept him from advancing to a higher rank.[6]

Gameplay Description

A Heavy Armored Operator, Echo's unique gadgets are two hovering drones called Yokai, which can stick to flat surfaces on a ceiling and cloak, as well as emit ultrasonic bursts that can disorient the enemy.

  • Much like Attacker drones, Echo throws the Yokai when deploying them.
  • While unable to jump like normal Drones, the Yokai have the ability to launch itself vertically upwards. If a Yokai comes into contact with a flat ceiling (can attach to certain slanted surfaces), it will attach and secure itself, as well as activating its second set of abilities: the ultrasonic blast and cloaking.
  • The Yokai have a 2-second cooldown between jumps, akin to normal Drones.
  • The Yokai's jump is limited vertically to 5 meters. This is apparent in rooms that exceed this height limit in certain areas such as the Lobby of Bank.
  • If a Yokai does hit a surface it cannot latch to, it will shake for a second before falling back down to the ground.
  • Tall flat surfaces (shelves, closets) provide good cover for Yokai. Echo can throw Yokai up to the spot, attach it to the ceiling, and hide Yokai by dropping back onto the shelf after using a blast.
  • The Yokai's ultrasonic blast is a pulse of sound that disorientates anyone caught in its wake, including other Defenders.
  • The blast only needs to hit an Operator on a part of their body to disorientate them.
  • Disorientation causes vision to be blurred a bit, with a shaking afterimage, darkened peripherals, and scattered dots of light, while also temporarily muddling their audio.
  • It takes around 10 seconds for affected Operators to recover from the effect. However, moving will lengthen the recovery time to up to twice its normal duration, on top of making the disorientation effects more severe such as darker peripherals and a more uncontrollable-but-steady screen sway.
  • The Yokai can only have up to two ultrasonic charges in reserve each. However, they can recharge these charges every 20 seconds.
  • The blasts' effective range is 14 meters. Although these blasts look like it has travel time, it is actually instantaneous when it hits anyone.
  • The ultrasonic blasts cancel most actions that their targets are performing when hit, such as Thermite deploying an Exothermic Charge or an Attacker planting a defuser in Bomb. Continuous actions, such as Montagne extending his shield, will stop their actions when blasted. One notable action that it cannot cancel is pulling the needle from Lesion's Gu mines.
  • The ultrasonic blasts also cancels Finka's Adrenal Surge if it was activated. However, another one activated afterwards will override the disorientation.
  • The Yokai's cloaking mechanism render them invisible after one second of being on the ceiling or a few seconds after using an ultrasonic blast.
  • Albeit cloaked, there is a slight rippling effect to it.
  • As the cloak works by copying the coloring of the ceiling above the Yokai, it is less well-concealed when latched close to special features or patterns on the ceiling.
  • The Yokai's cameras also have a limit to how much they can see. When on the ground, they can only see up to 40 degrees upwards. When attached to a ceiling, they have more freedom in surveillance as they can see everything below their level. All Defenders can use Yokai's cameras, but only Echo can control the Yokai drone.
  • Echo and his teammates can scan and tag enemies with the Yokai drones. Scanning does not uncloak them.
  • Even when dead, Echo and his teammates can still see through the Yokai's camera feed when in support mode.
  • The Yokai will lose signal and deactivate if they move outside the defending area and stays outside for more than 3 seconds. The effect is similar to the effects of Mute's Signal Disruptor on Attacker drones, with visual disruption before complete signal loss.
  • The line "LOSING SIGNAL, GET BACK INSIDE" will appear on the HUD when losing signal.
  • Echo is immune to Dokkaebi's Logic Bomb, having developed their systems in tandem with each other.
  • Echo also does not drop a phone, as he uses a wrist-mounted device to view cameras.
  • Even when Dokkaebi hacks into the Defender's CCTV system, she will be unable to grant Attackers access to the cameras on Echo's Yokai.


  • An exception to the Shock Wire destroying allied gadgets, the Yokai are able to touch Bandit's Shock Wires without being destroyed. Thus, Bandit can work with Echo without worrying about destroying the latter's Yokai.


  • The Yokai are remote-controlled electronic gadgets. However, it has certain characteristics that are shared with electronic gadgets that are "on-person".
  • Thatcher's EMP Grenades will only disable the Yokai for five seconds before reactivating. However, they will drop to the ground if they were attached to the ceiling when they were hit by the EMP, thus uncloaking the drone as well.
  • IQ and her Electronics Scanner can quickly identify the Yokai's location, as well as Echo himself while he's on his PDA, making her the most dangerous detriment to their survival.
  • Twitch's Shock Drones can destroy the Yokai with a single shock dart, but it is unable to see them when cloaked.
  • Cooked Frag Grenades can be useful for destroying Yokai if an approximate location is known, as falling down and moving away takes a considerable amount of time for the Yokai.
