For some time, Daemon found the Vongola Famiglia perfect and dedicated all his strength to it however, when Giotto threw away his military forces to prevent fight for self interest despite Daemon's protest, a rival Mafia Famiglia attacked Vongola territory, killing Elena in the process. Afterwards, Elena introduced Daemon to Giotto and he joined the Vongola. At some aristocrat party, he met Elena, who shared the same ideals as Daemon and wished to change it, and they eventually became lovers.

Despite this, however, he discreetly still treasures his bond with Primo and the other Guardians, evidenced by his treasuring of the pocket-watch that Primo gave to him and the other Guardians. It is also shown that he look down on people of the past, seeing them as merely a dead people who are buried in ground and felt somewhat insulted when Giotto and Cozarto mess with him by giving Tsuna their Flames that still live within Sky Vongola Ring and Earth Simon Ring, despite been already dead.

This devotion continues even after many generations and led to his decision to annihilate Tsuna's Family and recreate the Vongola in his image. He will do anything in order to create the Vongola that he desires and has no hesitation to kill innocent people whether they are children or women in order to achieve that. He truly believed that in Mafia world, power and greed are the absolute justice and thinks that Giotto isn't worthy to become the boss, which eventually led to his betrayal. He never wanted the Vongola Famiglia to fall apart, stating that weak people don't deserve to live, viewing Giotto s softness as disturbance for his ideal Vongola Famiglia. His devotion is strong enough to prompt him to be a member of Vongola for two generations.
