Was a bit confused when I started out too, so here's few heads up for people that want to play this game but don't know enough japanese, never played a gacha game before, or don't know how to download it.
Easiest way to install this on Android and bypass region restriction is to download and install QooApp from its website, then search for the game (just copy paste: フルボッコ) and install it. You can also use QooApp to manually update the game when needed.
You'll be given a starter team, but you can get more units by accessing the gacha screen. The types of gacha available are:
- Friend Gacha: gives weak units, but it's free and gradually recharges over time. (First option gives 10 weak units, second gives fusion/evolution materials)
- Rare Gacha: can get the strongest units with this, but you'll have to spend bokko (rainbow fruits). Don't spend those for now.
- Ticket gacha: exchange reward tickets for random units.
You'll also want to sell any unwanted high-star units obtained from gacha in order to obtain crystals: they can be spent in the gacha shop to buy units and other goodies. Rings can also be exchanged; these can be obtained as reward for main and special quests.
Use the highest star units you have for now. A unit with more stars have better stats, skills and an higher maximum level. 6* are the strongest.
Next you'll want to make a full team made of hot kemono girls/dudes (only do this when you can afford to make a party with good element variety and full of 4* units, at the very least). The first unit of your party is the leader, so pick a good one: every character has a leader skill which increase stats for every unit with a specific class/element. Making friends is useful since you can pick team leaders from other players and use them, too. Before starting a mission, you'll see two gauges under each of your units' icons: if both those orange/green gauges are on, said unit(s) will receive buffs from your team leader and your friend's, respectively.
Ways to power up your units:
- Fusing: fuse with other units to gain exp and level up. Metal haniwas (#354) gives a lot of exp (Sell the golden haniwas instead, for a lot of money)
- Evolve: Raises rank of your unit, with a subsequent increase in stats/skills/max level). Units must be at maximum level before evolving. Also note that not every unit can be evolved into a 6*: most 6* are available only when evolving units found already at 5*.
- Weapons: boost stat(s) of equipped unit, some weapons also change the projectile type. However, weapons may also increase the party cost of the unit, are destroyed when unequipped, and it's generally hard to find good ones compatible with your class/element.
- Status upgrade: your units will gain status points as they partecipate in battles. Those can be spent in the status screen of your unit to slightly increase any of the 3 stats (HP, attack, defense).
- Skill level: can be raised by fusing your unit with a scroll (#1152) and pink haniwas (#607, 608) together. There may be a chance for failing, but the game gives you the success% before confirming the fusion. Each SLv decreases the cost of active skill by 1, maximum SLv is 10.
- Limit break: mostly available for 6* only. Increases max level and also power up the leader/active skill (or even add extra effects to it). The yellow key icon in the status screen shows the requirements for LBing. You'll usually need the same/lower rank unit or, more easier to get, a jewel of a specific element. You can get this by evolving a broken jewel (daily login reward, special events, shop) using smaller ones (#2235, special events or shop).
- Red book (#2711): can be used to further increase maximum level; each unit can receive a max of 3 books. This is the rarest item, available through very few special events, so use it only on a meta unit (or on your waifu/husbando).
Correct power up procedure for 5* and under: only fuse and evolve. For 6*: do whatever you want in any order.
