OMORI Final Boss + True Ending (with Secret Scene)

Here's the final boss for a video game I love. Spoiler warning for the final boss and true ending.
I uploaded this video since all the other uploads of this I've seen are either in really long videos (upward of 1 hour) or have a watermark at the top.

If you don't know how to reach the true ending, here's a small guide for you:

1) Make sure you open the door for KEL on the first day playing as SUNNY.
2) On the day titled "ONE DAY LEFT", after SUNNY wakes up at BASIL's house, go to BASIL's room and choose the option to save him.
3) When the final boss defeats you (it's a scripted loss), the game will ask you if you'd like to continue. Select yes, and you've locked in the true ending. Selecting no will instead send you to the bad ending.

If you want the secret scene (which I've seen people call the "secret ending" or "basil ending"), you need to water BASIL's plants in every OMORI section of the game.
