1. General Info

    This guide is based on the patch made for the PS2 release which
uses Zohar's translation.
    The patch is currently at 88% translation which covers every
route completely except for Sakuya's which is at 60%.
     More info regarding the patch can be found on Akai Ito's 
VNDB page https://vndb.org/r40607 

2. Walkthrough

    Although Akai Ito has an integrated flowchart, the game uses a 
"seal" system to unlock certain routes which can be very frustrating 
since there's no clue for some of them. (In the past, SUCCESS also 
sold booklets separately which contained game tips.)
The recomended playing order is the following:
Uzuki -> Tsuzura -> Yumei -> Sakuya -> Secret

2.1 Uzuki true route

      No seals required to play this route.

Day 1

I want to ask the station worker something
I decided to have him bring me to the hotel.
I gather my courage and follow through!
Now that I think of it, wasn't there
I bow my head in a nod.
Check it out.

Day 2

Tell her about meeting him.
Chase after her.

Day 3

I'm not convinced.
I'm worried about her.
Chase after her.
I'd better set the charm.
Uzuki-san!?
If it's just to my room, though
Sleep in the futon together 

Day 4

Proposal withdrawn.
The world shifts to white - white flowers
I promised I'd believe in her.

2.2 Tsuzura true route

      No seals required to play this route.

Day 1

I've already checked everything. It's fine.
I shake my head from side to side.
(Right after this decision is the 'My Scars' scene
which also acts as a seal for Yumei's Route)
It'll be fine.
I'll go eat them with Tsuzura-chan.
Apologize honestly.

Day 2

I'll go look for Tsuzura-chan.
But I want to do something.
I'll go myself.
Mmn~?

Day 3

I'm worried.
Well, let's go, then.
I wonder what they're talking about.
We're going.
But you really hate being alone, don't you?
Don't resist.
Strengthen the seal. 

(MAKE A SAVE RIGHT HERE AT THIS DECISION
 BEFORE YOU PICK "STRENGTHEN THE SEAL"
- you are gonna want to choose the Search for the Mirror option 
later for unlocking the secret route Seals - after picking
'Search for the Mirror' simply choose ''Doing that would 
be too sad'' and you will get the first requirement 
for the secret route - the other requirement is in Yumei's Route)

I don't want to forget! 
(The other choice is 'My consciousness - won't-' 
which you will auto pick first time through the route - after unlocking the 
seal by viewing the ending on Tsuzura's Route simply reload from Strengthen
the Seal and pick 'I don't want to forget' and you will get the True Ending)

2.3.1 Yumei seal unlock

Day 1

I want to ask the station worker something
I decided to have him bring me to the hotel.
I stop short out of embarrasment.
I bow my head in a nod.
Write it off as my imagination.

Day 2

I'm not scared. I'm not scared. (Right after this decision the scene you 
need to unlock the Seal will play)
"Ah! No! Not really!" and then leave.
Don't call her.
Let's not bring it up.

Day 3

Go Home.
Note: next time you try going through this route it will have change on the
second day after 'Let's not bring it up' due to the seal unlocking so don't
 expect the same scene of Nozomi and Mikage going full vampire on Kei's neck.

2.3.2 Yumei true route

         After you've seen the scene 'The Oni and the Oni Slayer' from Uzuki's
route and the 'My Scars' scene from the Tsuzura/Sakuya common route you 
have unlocked Yumei's true ending.

Day 1

I want to ask the station worker something
Even without the bus, I can still
On second thought, please take me back.
I shake my head from side to side.
Write it off as my imagination.

Day 2

I'm not scared. I'm not scared.
"What a coincidence," and give your name.
Don't call her.
Let's not bring it up.
Touch the hell out of them.
I'll let her drink my blood.

Day 3

Tell her about the dream.
I can't just take this at my age.
There's no real helping it so bear without.
I'll let her drink my blood.
Don't go home.

Day 4

Make her drink my blood.
Clean the house.
Something's not right.
But, I can't help but feel sorry for them
(This also unlocks one of the two reqs on the seal for the secret route)
I'll let her drink my blood.
I'm saving Onee-chan, no matter what!

2.4 Secret route

    You need to see the 'Aggressive Tactics' scene from the Tsuzura
route and the 'A Multitude of Fireflies'  scene from the Yumei route
in order to unlock this route.

Day 1

I want to ask the station worker something.
I decided to have him bring me to the hotel.
I gather my courage and follow through.
Now that I think of it, wasn't there
I bow my head in a nod
Write it off as my imagination

Day 2

Tell her about meeting him.
Chase after her.

Day 3

I'm not convinced.
Doesn't matter
Did I brush my teeth?
I'll make Nozomi-chan test her.

2.5 Sakuya true route

      You need to see Uzuki's true ending to unlock this route.
      I left Sakuya for last since at this moment only ~60% 
of her route is translated.

Day 1

I've already checked everything. It's fine.
I bow my head in a nod.
It'll be fine.
Nighttime snacks are the figure's enemy.

Day 2

You can't fight on an empty stomach.
I'll get something at the convenience store.
I'll go myself.
It's just a dream.
The snake! Poison!?
Please do it.

Day 3

But still.
I'll let her drink my blood.
If you really mean "nothing but"
???????????????????????

Translation SoonTM
