Seeing as literally none of these threads are complete, there won't be an official verdict until at the very least the majority of these threads are completed. Most preferably the combat threads. Now, I will give some insight in terms of what you should expect:
Tier: That's a lot of Platinum Points, but that also doesn't matter that much because the validity of an upgrade is still entirely dependent on the progression of the threads, so on so forth. To which, I'd say it definitely does not justify a 5 minor-tier upgrade, and especially not an upgrade all the way up into 0-tier realm, so a tier boost application won't be reaching into there.
Skill Sheets: Expert doesn't exist anymore. There was a large update cutting back on the skill levels, all explained
HERE, so some of these aren't valid. Having graded the character, I do know his general thematic, and I'm comfortable with approving Zanjutsu and Strength to be at Elite, as on top of these threads, I also do think that without the existence of Expert Tatsuya would more appropriately be at that level in the two traits. Regarding Durability, I'll have to see the completion of some of these threads before I feel comfortable being okay with upgrading them.
Future Sights: It should be clearly asserted that this ability does not actually make him capable of seeing the future, so things that have nothing of particular warning or preemptive visual cues should be something he anticipates unless some other cue was given. Additionally, if this ability doesn't function of focus, I'm gonna need some more information on it that explains why or how it works and separate from focus.
