The achievement is unlocked following a cut scene between Nozomi & Ryo when Ryo discovers the missing kitten. Nozomi, we learn, had been looking for the kitten too and comes upon Ryo & the newly found kitten. The achievement pops following the ensuing conversation.
This is missable. The event is triggered when Ryo wakes up and looks at his bank statement adding 35,000 JY to his account. There is a very short window where Ryo can be informed the kitten is missing giving him a short side quest to find it. The quest will only be available if Ryo has interacted with the kitten sufficiently for her leg to have healed. If her leg is not healed, she cannot wander off and get lost.Prerequisite
: Early in the game, Megumi tells Ryo about a kitten she found and is keeping in a box at the shrine. A black car killed the kitten's mother and injured the kitten's leg. As part of the normal story, Ryo feeds the kitten some dried fish he finds on the shrine's altar. The kitten's leg will heal itself provided the kitten is fed. Ryo should purchase dried fish (300 JY for 4 servings) or milk (100 JY for one serving) from the Tomato convenience store in Dobuita. Ideally, if you want to witness all possible interactions, you should visit the kitten morning, noon, and night; feeding her each time. You feed the cat by selecting a food item from your inventory while standing in front of the kitten and pressing
You do not have to be particularly diligent. The kitten's leg will heal after being fed only a couple of times. If you don't feed her but name her and pet her, it is also possible that she will get out of the box but her recovery will be slower. It is best not to risk it. If you interact with the kitten regularly, you will come across a couple of indicators the prerequisites have been met. Once the kitten starts to recover, when Ryo enters the shrine a cut scene will occur. Ryo will tell the kitten they are alike--they each lost a parent on the same day. Another indicator occurs during an afternoon feeding. A boy and a girl comment on how well the kitten is eating (or drinking milk) and tell Ryo they have been feeding her cheese. Ryo talks about the importance of nutrition but cautions against over-feeding.
If you have interacted with the kitten sufficiently for her leg to recover and Ryo stops by the shrine the morning when Ryo's funds increase by 35,000 JY, Megumi will tell Ryo the kitten has gone missing. Exhaust all conversation choices with Megumi. Walk back in the direction of Ryo's residence. At the top of some stairs to the left you should hear the kitten's meow. If you do not, go back to Megumi for further conversation. When you hear the kitten's meow, go down the steps and the kitten will be at the bottom. When Ryo looks at the kitten, Nozomi shows up and has a conversation with Ryo. The achievement unlocks at the end of the conversation.
If Ryo stops by the shrine following the increase in his funds and the kitten is still at the shrine, quit the game. Hopefully, you have a save before Ryo shows the Phoenix mirror to Chen. Load up the best available save. Before going to see Chen, buy some dried fish and milk and start feeding the kitten until you get one or both of the indicators described above. Once you do so, continue with the story. After you show the mirror to Chen, the scene will end with Ryo back in his bedroom. He will have a dream and wake up looking at his bank statement. Ryo will not be able to leave the residence until he speaks to Fukuhara. As soon as that event concludes, leave the residence and go to the shrine in Yamanose to find out the kitten has wandered off.
