 * "You look like you might know exactly what to do with this."

Heart Reactions

 * "How truly amusing."
 * "Done already? A shame, I wanted to continue this."
 * "I grant you this freedom to do as you please only for now."
 * "Very good. Just as I expected."
 * "I must thank you for showing me such a good time."
 * "Now then, how shall you please me next?"
 * "You wouldn't mind if I touched you, would you?"
 * "The feel of another's touch is refreshing. I feel splendid."

 * "I thought I would have more fun. I guess I expected too much."
 * "It's clear that you don't appear to value your life."

Perfect Sequence

 * The more I know about you, the more drawn to you I feel. Nothing can captivate me as you do."

Heart Reactions

 * "I had been wanting this. Thank you."
 * "You know exactly what I like."
 * "I'll be sure to boast to Lucifer that you gave this to me."
 * "How Splendid! You are quite good at pleasing me, aren't you?"
 * "This looks delicious. Although, I may only feel that way because you made it."
 * "You've made me want to give you something too. I hope you're looking forward to it."
 * "I am pleased just knowing you thought of me while getting this."

Sparkle Reactions

 * "If you say it's that good, I'll gladly accept."
 * "Is this going to be some kind of "hilarious" trick?"

Sweat Reactions

 * "Why would you think of giving me this?"
 * "I...I'm a little unsure how I will use this."

Christmas Holidays

 * "These are Christmas ornaments? I've been seeing a lot of these in the Devildom. It would be interesting if when they break, candy came out."
 * "I thought that I'd put a giant tree in the castle... ...but Barbatos stopped me. Apparently 300 feet is too big."

Winter Fair

Valentine's Fair

 * "Here is something for you. Happy Valentine's Day!" (Demon Voucher)

Dango Over Flowers Fair

 * "I hired a professional confectioner to design a sweet based on the three worlds. Receiving such a special treat as a Three-Worlds Dango from you, I'm not sure what to say."

 * "Now that spring's here, I hope that we can get to know each other better this year. Shall we take a walk around the castle? The cursed baby blue eyes are in full bloom at the moment." (Demon Voucher)

Talkative Music Note Fair

Horror's Horror Cherry Pie

 * "A seasonal cherry pie? Mmm, looks good. I've only ever had the bloody cheesecake from Horror's Horror, so this is quite exciting."
 * "Recently, I've been in love with Barbatos's cherry devil crush sauce-covered steaks. It's your turn to cook tomorrow, right? It's so good, so give it a try making it, will you?"
 * "You have no idea how thrilled I am to learn about the Devildom from an exchange student of all people. I'll have to brush up on my human world knowledge so I can teach you something you didn't know too." (Demon Voucher)

A Summer Fireworks Frenzy

 * "There are such thinks as hand-held fireworks? These look quite fun. Thank you."
 * "There used to be a fireworks display at Siren Beach. Lotan was so frightened it wrapped itself around Leviathan. Those were the days."
 * "As thanks, have this. Also, I wish to light these Frenzy Fireworks with you too. If possible, I would like it to be just the two of us. Will you make the time?" (Demon Voucher)

Juicy Revelation Tomatoes

 * "If these aren't Revelation Tomatoes, huh? Thank you! Barbatos always stops me from getting these. He thinks the future Demon King shouldn't have to reveal anything."
 * "I sometimes have the brothers tell me about Lucifer when he was an angel. Because no matter how much I ask, Lucifer never tells me himself. Please, don't tell him."
 * "Actually, I don't want you to go home today. So this is more of a request than a revelation. But this is my secret. I'll let you decide what to do with it. But I expected a good answer." (Demon Voucher)
