You may spend time with your Waifu pals at the ETHsekai Harem Club, whether you're exploring or just holding them, and they will be just as busy as you. The ETHsekai allows you to bring your Waifus to life, from giving them a distinctive name and backstory to giving them voices. Waifu Harems may also be viewed and showcased in a separate showroom. Upon the completion of the launch, these functionalities will be made available to users.
