Chen Yu returned after handling affairs in Fukuoka, so naturally, Ni Nasu no longer needed to disguise herself as him. Although he was only there for a day, it must be said that it was fortunate he had Ni Nasu as a contingency plan to impersonate him; otherwise, there was indeed a risk of mishap.
Now that he's back in person, and since yesterday was relatively uneventful, no one would possibly know that he had made a trip to Fukuoka, dismantled the Tenmangu Shrine, and summoned a brand-new demigod during his visit.
Speaking of the matter with the demigod, Chen Yu had already announced publicly through Monk Xinyuan that there were only five demigods around him, plus the so-called "temporary" summon, Kirov, making a total of six demigod-level ship-girls. As such, he no longer enjoyed the prior perks where ship-girls brought him breakfast every morning as was the case a few days ago.
