My adorable friend, Baron

Aiko and Spank play happily in the summer sea. Then a puppy that looks just like the dead Papi appeared. On the other hand, Aiko meets Seiya Tsukahara, an unidentified boy. However, this Seiya was hateful, and as soon as I met her, she had a big fight with Aiko. And he was the owner of a puppy (Baron) similar to Papi. Aiko is somewhat depressed for Spank, who is overjoyed to have a new younger brother. That's right, Seiya moved from Tokyo and became a student in the same class as Aiko. " Nice to meet you, seaweed hair" Somehow difficult mood in the future.
