This rather large building with many windows, it by far the largest library in Konoha . It is the home of Sai Li and what ever strays he brings in. The living space off to the left is about 45 sq meters.
The entirety of it's collection being: 30,724 book of fiction; 21,781 non-fiction book; 1,273 scrolls having to do with different techniques, 549 essays in binders with each page either laminated or in a page protector; 6,576 comic books; 5 copies of the complete works of Shakespeare; 40,000 or so snippets of poetry, short stories, and written wishes (most of which were from young girls wishing for a boyfriend) those who've visited in a couple hundred binders due to the fact the a rumor was spread that placing your wish in one would grant it; and more newspapers than one could EVER be bothered to count.
for Spatial Jutsu; Push it's not really specified how powerful it is so I'd say something like for every 10 chakra the surrounding object would be moved 3 feet or add a predeterminer distance like 5 or 6 feet with a flat rate of chakra consumption.
rambling about science that i disregard anyway: I would have to say Spatial Jutsu; Black Hole it should cost at least 80 chakra I mean, have you ever studied black holes. being sucked into one of those is about the worst fate you can be faced with. Not to mention the fact that if you get anywhere near a black hole.... you're dead... that's it... game over, go make a new character dude.
but other then that there are no problems and I approve. (non-scientifically XD)
name: Mother's Embrace Clan: None effect: A 5 meter diameter orb is created in which warm chakra surrounds everyone with in it, it heals slowly over time and helps all, but the person using the jutsu, to gain chakra back at a quick rate (10 per post) damage: none chakra cost: 30
