Kiruru

I don't think it is possible to uncensored the scenes in the game. It's part of Japan's censor law or something.

Not sure if it's my computer, but the music seems to cut off, slow, and staticy at parts.

Just because there hasn't been any progress doesn't mean that he's dead. And it does SAY on the website that he has a job that involves him working from 12-13 hours.

By completing at least 3 main heroine routes (pretty sure).

Sakura Iro Quartet would be nice.

Are you sure? She appears on my selection screen and I've played through all the translated and sub routes

Ah that's good news!

Unfortunately, Miyako route still at 50% translated.

Well, certain number of hearts will depend how close the characters are to you. For example; Miyako usually has 2 hearts since she's obsess with you and Chris usually has a ton of hearts since she's a little tsundere. You don't have to restart, just go back to start (if I remember correctly) -> skip prologue, and a character selection screen would appear.

Not to forget Moro, Gakuto, and Capt route

This may be a noobish question, but
