My Japanese is horrible, so I couldn’t translate all of this. Here’s what I can translate, going from right to left:
Introductions by Alas Ramus (Try your hardest~!)
Sadao Maou (Demon King Satan)
Papa~! One thing he can do is try his best! We spend a lot of time together! [Translator’s note: That sentence literally means ‘much together’, but I put it into context.] I love him!
Emi Yusa (Hero Emilia Justina)
Mama~! She and Papa get into fights, and we spend a lot of time together! I love her! [T/N: Not sure whether I translated the first part of the sentence properly.]
Chiho Sasaki (Sasahata [T/N: It could also be Sasahan or Sasahon, but i went with Sasahata.] North High class 2A)
Chi-nee-cha! [T/N: Sister Chi(ho)] She smiles a lot and ____ a lot. [T/N: Not sure what ‘fukafuka’ is.] She’s friends with Papa and Mama, I love her!
Shirou Ashiya (Demon General Alciel)
Alciel! He makes meals! They’re tasty! He also cleans! I love him!
Hanzo Urushihara (Demon General Lucifer)
Lucifer! What’s a NEET? Lucifer does absolutely nothing. [T/N: Those last two sentences may not be fully correct.] I love him!
Suzuno Kamazuki (Doctrinal Correction Council Member Crestia Bell [T/N: …or something like that…])
Suzu-nee-cha! [T/N: Sister Suzu(no)] She has pretty clothes. She also makes meals! I love her!
