Titre original : My Grandpa is on a Rampage!
Aki reacts with "Jejeh... Jeh!" as she realizes tomorrow is her birthday. But the third "Jeh" is for something else... Taneichi had earlier given her a wrapped item. Before he could explain what it was, they were interrupted by Isono-sensei ("Did you record the show?!"). So in her room, Aki opens the gift and found a misanga bracelet inside (made by the Ama-sans at the Co-op). "Did Taneichi-sempai knew it was my birthday?" She wants to thank him but does not have his phone number. She calls up Yui instead. "Is it really for your birthday?" Yui says, doubtfully. Aki reiterates: "But it's a misanga!" Aki thinks that the gift could mean something promising - love-wise*. Anyway, Haruko comes home finding her husband at the house. "I told you not to come!!" Aki wants to talk to her mom about her birthday but Haruko dismisses her off saying now is not a good time. At night, Aki sleeps in the 80s room (which is by now her official bedroom) and dreams of giving a misanga to Taneichi but he turns into Isono. She wakes up to find her father sleeping next to her and she (as well as the rest of the family) is put off by him. The next day, Aki finishes her train job a bit late and is told by Daikichi to wait at the shop so he can get his car (to drive her home). It turns out everyone is in the shop to give her a 17th birthday surprise party. They bring her an Ama cake adorned with chocolate sea urchins (really cute!). Then Yui brings in Taneichi which rouse some teasings from the rest. "Is he perhaps your rumored Helmet Sempai?" (lol) They also did not spare poor Hiroshi-kun from their good-natured ribbing: "Look look, Stove-san is red with anger." "Is this Stove VS Helmet?" (Haha!) "I'm okay. I've already gotten over it," Hiroshi says sullenly as he gets himself a long drink. (XD) Aki and Taneichi have a moment alone together outside the shop as the party gets going inside. He tells her the bracelet is actually for "goodluck" for her upcoming qualification exam. Aki asks him shyly "If I pass the exam, can you go out with me?" Taneichi does not give a straight answer ("But where can we go on a date around here?") but as he leaves, he tells her with a smile: "I'll give it a good thought." Aki goes back inside the shop. Chuubei and Natsu are singing a duet. Afterwards, Chuubei invites Haruko to sing a song which she declines. But he insists: "You used to sing for us before I go leave the next day for the ocean." Haruko's husband chooses a song for her to sing. The title is "Shiosai no Memory (Memory of the Sea's Roar)." As the opening chords is heard, others say "Oh, I miss that song..." "Wasn't it a song from an old movie?" Haruko and Masamune exchange a meaningful glance. "No, no, no, I can't," she refuses and puts down the microphone. "Tsk, you've changed," Chuubei says, irritated. "In the past you said you wanted to be an entertainer in Tokyo." He turns to Masamune. "You know what? She said she wanted to be an idol singer. That's why she ran away from home!" Both Aki and Yui give out a perplexed "Eh?" as a sudden uncomfortable silence fills the room.
