A Japanese Apple account. You have to have one in order to download the game anyways. That Apple account is connected to the game, so I don't believe it will work if you use a non-Japanese Apple account? I'm not entirely sure actually.
You may be asked to input your password a few times while doing this entire process. It's for security stuff!
A Japanese iTunes gift card. You can buy these on various online sites, however the one that I used is JapanCodeSupply. I got my code within the first few minutes of me purchasing it and it worked so, I like it.
Once you buy one of those, you have to insert the code into your Japanese Apple account.
To do that on your iOS phone-, go to the App Store (Blue), Updates, the person icon at the top right- if you added an icon to your account that will show here, Sign out if you're currently not on your Japanese Apple account and then login to that, once you're signed in press Redeem Gift Card or Code, insert your code and then press Redeem. You should get a screen that says it was successful if you did it correctly! Press done after you're done inputting codes.
At this point you could choose to spend your credit on other things. Buy songs from the jpn iTunes store or buy premium currency in another game. But since this is a guide on how to kakin in i7, go into i7!
Once you're in i7, you could either go to the Shop and press the Stellar Stone icon or press the plus sign (+) next to your Stellar Stone count at the top.
You will be asked to input your birthday here if you haven't put it in yet. Why is this here? There's a spending limit of how many Stellar Stones you can buy per month. For the record, you don't get anything on your birthday currently after inputting this.
If you're under 16 you can only buy 5,400 Yen worth of Stellar Stones per month. (220 Stellar Stones)
If you're 16-20 you can only buy 21,600 Yen worth of Stellar Stones per month. (880 Stellar Stones)
If you're over 20 there is no limit.
There's going to be a scroll down I believe if you have to insert it in. If you see 20XX that's going to be the year, if you see a scroll down that goes all the way to 12 that's going to be the month and if you see a scroll down that goes all the way to 31 that's going to be the day.
After that you will see a screen like this!! These are the amount of Stellar Stones you will gain and the amount it will cost. For example, if you were to press the 40 Stellar Stone button it would cost 1200 Yen- roughly $12. Pick your desired amount! However do note that there is a spending limit depending on how old you are.
Once you press your desired amount- you will see a screen like this. How many Stellar Stones you're going to gain and how much it will cost plus your current Stellar Stone count and how much you will have after the transaction.
The X Button off to the side will cancel
The Pink button will continue the transaction
After pressing the pink button you will see a screen like this, press Purchase and it will prompt you to input your password- it's for security.
Press Cancel and it will cancel the transaction
After that, you will get a Loading screen and either of these two screens.
And that's all you have to do in order to buy Stellar Stones for iOS!
What you will first need is pretty simple, a Google Play account. Every Android device that I am aware of required one just to boot up the device and purchase apps both free and paid.
Once you have that covered you will either need to a) buy a regular old (not Japanese) Google Play card and hook it to your account or b) hook your debit or credit card (debit recommended) to your account.
With that you're pretty much good to go, just hit the + button next to your Stellar Stone count to access the menu where your options of 3, 10, 20, 160, 110, and 220 stones are presented to you, select your desired amount. You should be presented with a pop-up telling you how many stones will gain, click the only button outside of the close button. Next will bring up the Google Play tap-to-buy menu, tap the green button and your payment will begin to process. After that you should get a window that is telling you it went through and your stellar stone count should have gone up accordingly.
Redeeming Serial Codes
These can also be obtained multiple ways, but they involve buying the item that it is bundled with. For example, the special Tenn and Riku cards drawn by Arina-sensei were both bundled in the manga and novel when they were released. Sometimes magazines also have present codes. CDs are another way to obtain them; for example the MEZZO"'s Koi no Kakera CD contains a special present code for a special card! Either way you will have to buy the actual item that is associated with it.
How Redeem Serial Codes
First you must go on the official website. The present code box is to the side circled in red.
When you get to the page you must enter in some information. The first option is the campaign box, which is basically asking “Where did you get this code from?”
Now you must give your Game ID (there’s a tutorial on how to do so on the page itself) and the present code you have obtained. Then just confirm and if all of the info is correct it will be rewarded to you in-game via mailbox!
Owned Items: This isn’t used very much nowadays but these are where items like the Nanakore are kept.
The first is item is the Nanakore
The second is the Puchinanakore
The third is items like Kinako Bread which gives 20 LP (Kinako Katsudon? in this case... It does the same thing). These items are only available until that event is over. You can't save it in the mailbox.
How to use a Nanakore/Puchinanakore
Press the Pink button off to the side that says Accept.
You will then be greeted with the Nanakore's content.
This image is the contents of what was in the 3,000,000 download celebration. You had to do a 100 Paid Stellar Stone pull in a paid audition in order to get it and it could only be attained from May 17, 2019 to May 27, 2019. It also expires on November 17, 2019- Normally Nanakores don't expire, but this one is an exception.
Tap on the card you want to obtain. Do note that the Nanakore will go away as it has been used.
You will then be given a screen like this. It shows the card's base stats plus the stats it gets when fully special trained.
Back in the upper right corner will take you back to the first screen where you can reselect your choice.
The pink button will confirm your choice.
You will then be given a screen like this. It shows the card you're going to get and the your Nanakore count after you obtain it.
Pressing the Blue button will put you back on the stats screen.
The pink button will confirm your choice.
Congratulations you have now used your Nanakore.
Example of an Event Banner
Events are special periods of time with center-themed cards.
They happen at random- they used to happened once per month, however they now happen usually after an event has already ended with no breaks in between.
Events usually last up to 8 to 10 days max.
Sometimes the cards released before the Event has special features that come with them
Special Sound Effects, Event Bonuses, ect.
Events follow a ranking system where the lower you are rank wise the more special the stuff you can get. You'll only earn the items you earned at your end rank.
Besides from the ranking system, there are also set point rewards (such as UR items and Pudding) that you gain at different point tiers.
