- [Under Yato's guidance, Yukine makes his first borderline]
- Iki Hiyori: Wow! This is a borderline?
- Yato: Yep, it acts as a boundary between self and others. Phantoms can't cross it.
- Iki Hiyori: Can you do this too? C-can I?
- Yato: You and I can't. Borderlines are a Regalia power. Any Regalia can make them, but creating one this strong right off the bat? This is definitely a first out of all the Regalias I know.
- Iki Hiyori: I'm going to look after Yukine!
- Yukine, Yato: Huh?
- Yato: Are you crazy? He can't stay with you.
- Iki Hiyori: You're the one he can't stay with! You don't even have a place to live or a semblance of a stable life, what with your ex-girlfriends, your affairs, and your friends with benefits! Your depravity knows no end! You're unfit to be his guardian!
- Yato: Unlike this house, shrine grounds and buildings are sacred territory. They keep us safe from Phantom attacks.
- Iki Hiyori: Even so...
- Yato: Night is the time of devilry, when Phantoms that lurk in the darkness come out. I doubt he'll be able to handle it.
- Iki Hiyori: Huh?
- Yato: Yukine, you see... is... afraid of the dark.
- Yato: Master and Regalia share mind and body. I get stung every time Yukine gives in to temptation. That's how things work for Regalias and their masters.
- Iki Hiyori: Then, does that mean Yukine got stung too when you swiped some of my father's drinks?
- Yato: Nope. The pain from deranged thoughts only goes in one direction - from Regalia to Master. Regalias used to be people, and people sin. Resentment, fear, envy, desperation, sadness, greed - these and countless other things give rise to temptation. The sin of acting on it turns to pain, which is how we learn, via Regalias, what is right and wrong.
- Yato: People decide what's right and wrong, but those things don't apply to gods. In other words, gods can do anything they want, including hurting someone or taking their life.
