Echocalypse: Scarlet Covenant is a role-playing game for Android devices in which players become an Awakened One and assemble a team of heroines, referred to in the source as Kemono girls. The description presents team building and battles as the central activity, supported by 2D anime-style graphics and a mix of action and adventure elements.
Building a team around each heroine's skills
The source states that each Kemono girl has her own proficient skill, and that players should understand each heroine's skills and powers to assemble a team capable of defeating various enemies. Players can choose the heroines that suit their preferred battle style. The description also says the game provides lineup combination suggestions intended to improve battle efficiency, but it does not explain how those suggestions are produced.
Strengthening heroines and raising Affinity
According to the source, Kemono girls can be boosted in several dimensions to improve their combat Attributes. Romantic dates with a chosen heroine are described as increasing Affinity while also enhancing character Attributes. The description does not state the numerical effect of either action, so their exact impact on battle performance is not documented.
Character levels are described as supporting one-click inheritance, which the source calls lossless. This feature is presented as a way to switch lineups quickly. The description does not define further rules for how levels transfer between characters.
Battle speed options
The source says that automatic battle and skip battle functions can be unlocked, and that they can greatly shorten battle duration. Some Story stages support skipping battles, and more daily gameplay supports quick blitz, which the description says helps players avoid repetitive fights. The source does not list the unlock requirements for these functions.
Progression through levels and story
Progressing through levels advances the story and unlocks more powerful heroines. The description also states that completing levels in an earlier chapter opens new chapters. Together, these statements tie story progress to access to new content, although the source gives no further detail on how unlocking is sequenced.
Drawing heroines and rewards
The description outlines a card-draw system in which players receive 10 free draws each day, supplemented by resources. It also mentions a self-selection option of one hundred draws and states that players could obtain top-tier SSR characters during the first week of beta. These are presented as promotional reward descriptions. The source does not specify draw rates or the exact terms of each reward.
Additional game modes
Beyond story battles, the source lists several modes. An arena allows players to compete against others, and periodic fights with BOSS enemies at the port are described as giving rewards. A dormitory can be customized for the player and their heroines. The Syndicate is a social feature for making friends and exchanging gifts, and the description says members can jointly recharge the High-energy Reactor for high returns. The source does not explain these modes in further detail.
Event and update content described in the listing
The description covers several time-sensitive additions. A 2nd Anniversary login event offers seven days of rewards, including an SSR Oath Outfit Selection Chest and an SSR Case Selection Chest. A Wind-type limited MR Case, Kala, is introduced with an elemental attribute and a Pneuma Skill and Pneuma system. The UR Witch Lilith can be obtained through the limited-time mode Phantom Break during an event. The listing also mentions the Main Story Update and the PvE mode Euphoria City. Because these are described as limited-time or event-specific, their availability depends on the periods stated in the source.
Limits of the available description
The description is promotional in tone and does not provide combat formulas, drop rates, draw probabilities, or detailed difficulty settings. Its tips section uses general phrases such as unrestricted strategic freedom and immersive character interaction. These phrases describe the intended experience but do not explain specific rules, so they are not treated here as confirmed mechanics.
