Keiko-chan's Secret

About
Keiko-chan's Secret is a surprisingly large adventure game for the time, considering it's one man dev team of Biccs Maiko. Champion Soft functioned as publisher for this title.

It's also one of the few games which had "sequels" in the form of the 3 Keiko-chan After programs.

Story
Keiko-chan is a college student living in a nearby apartment complex, she's also your private tutor. One day while peeping on her using your binoculars you saw something happen which you could quite believe.

It's up to you to figure out what happened to Keiko-chan, you might even get rewarded.

Gameplay
The game is mostly an ADV game, at the start you'll be answering by using choices. This gets mixed up a bit by an exploration section using that same ADV mechanic for conversations. At certain points of the game you search through a room using a cursor. Movement is the same (2468), but you press enter to investigate an object.

This is then followed by a text parser ADV section where you investigate a house (and the outer area at first) which also uses the searc mechanic. The adult section follows if you are of age and is done by text parser as well.

It asks for you DOB, you need to be 20 at the game's release.

It asks for a year/month/day in the showa period and then asks when you were born.

It was the year 59 in 1984, but it shouldn't matter. just make sure you type a double digit number with a difference of 20 years or more (including month and day).

741-953 till you get through

Apartment building section
Your goal here is to find Keiko-chan's room (it starts out locked).

To do this you need to first find and talk to a "nude model, fashion model or fashionable girl". This will then allow you to find the photographer which leads to Keiko-chan's door being unlocked.

Rooms are randomised, you control yourself with 2468. The option for the door are:
 * Knock
 * Open door
 * Use intercom
 * Leave

For elevators they are: You then use numbers to indicate a floor with 0-6 (0 basement and 9 cancels). The left or right elevator thing doesn't matter.
 * Left elevator (UP DOWN or leave)
 * Right elevator (UP DOWN or leave)
 * Leave

You can stack + or - events if you want.

Check another place, N and it should take you to an ADV section

ADV section
This section is a text parser ADV section, so the text is kept in Japanese except for instructions for the player (i.e. look for X).

Note: The dog wants a randomized food item. If it doesn't work, go back (or reload) and get the other item.

Here's an (untranslated) trick to immediately start here for the disk version:

ゲームをスタートして「数日後…」というメッセージが出たらホットスタートをかける

（ＳＴＯＰキーを押しながらリセット）

RUN "K2.BAS" 【 RETURN 】

ゲームが始まったら再びホットスタート

RUN "K4.bas" 【 RETURN 】
