Just as peace is beginning to reign in Azusa's home, a young elf named Halkara shows up pleading for her help. Halkara says that an energy drink she made angered a terrifying high demon, Beelzebub, who is now out to kill her. Azusa would prefer to avoid anything that might ruin her slow life, but she can't just leave the poor girl to die, so she reluctantly agrees to shelter her...
I hope the barrier I put up 
this morning keeps her away.
Hoffentlich wird die Barriere, die ich heute
Morgen errichtet habe, sie fernhalten …
Si seulement ma barrière de ce matin
pouvait la retenir…
Spero che la barriera che ho piazzato stamattina 
la tenga fuori.
Espero que a barreira que
fiz hoje de manhã a afaste.
Надеюсь, её сдержит барьер, что я возвела утром.
