Bought some theo for the Hyper Variety Pack, and got
extremely lucky.
10/10, will get the Hyper Pack again.
Though, since it's a theo offer, you can just save up theo earned in game to buy it, which is great! It's most definitely the best thing to save up for, hands down, and I recommend it to anybody who is good at saving up.
Also, I don't know if it's been said anywhere yet, but upgrading Fukua's marquee reduces the amount of health lost necessary to gain bonus damage/reduction, down to 5%* at fully upgraded.
Another thing to mention is that she was one of only two shinies I received from all 154 relics, the other being a Headstrong, so shiny odds are definitely very low.
