Alchemy Stars is a strategic roleplaying game featuring a diverse cast of characters that you can recruit. You might be wondering which units are viable, or perhaps you’ll want to get to know more about the potential of strong units. With different star ratings in the game, one of the best recruits that you can get are 6-Star characters.

There are four main elemental attributes that are available in Alchemy Stars. You can have attributes for Forest, Fire, Thunder, and Water. These have different 6-Star units that you can choose from. In this page, we’ll be checking more about the Forest attribute character named Hiiro.

Here, we’ll be checking out Hiiro’s profile, skills, equipment, and breakthrough bonuses. We hope that this page will help you out learn more about this character in case you will try to get them in your team. Let’s check what’s in store upon acquiring this character.

Note: You might notice that the profile describes a secondary attribute. Whenever you recruit an Aurorian for the first time, you’ll be able to view their primary attributes only. The secondary attribute is only acquired once you have obtained the max level of Ascension. Legendary Aurorians come with their max ascension level however. We also didn’t include their Atk, Def, and HP since the values can change over time depending on the game updates.

In Alchemy Stars, Hiiro is a Forest unit with a Detonator role. As such, the skills that you’ll be able to obtain lets you deal damage versus enemies in a select area with the added benefit of destroying obstacles such as rocks. Hiiro also has the capability of converting tiles to enhanced green tiles.


Active SkillConverts any 2 chosen tiles to enhanced Green tiles and deals 200% damage to enemies in cross shape to the maximum range.
Skill Cooldown3 Rounds
Chain Combo (2 tiles)Deals 160% damage to 1 surrounding cluster.
Chain Combo (8 tiles)Deals 165% damage to 12 tiles in a diamond shape.
Chain Combo (12 tiles)Deals 170% damage to 2 surrounding clusters.

As a Detonator, Hiiro’s job is to be able to deal damage to enemies in a specific range. Once her skills are activated, she can hurt enemies with an area of effect, as well as remove any obstacles that can be destroyed such as rocks. This way, you won’t be hindered by objects blocking possible paths.

Her active skills provide her a secondary role as a converter since she can convert 2 chosen tiles into green ones, at the same time providing strong damage in a cross shape.

Chaining green tiles that are longer will provide the best benefits for her chain skills. The damage she provides are based on patterns and can hit clusters or diamond shapes. Thanks to her active skill, she’ll be able to get green paths easier.


Equipment SkillHiiro enters Duel stance at the start of the round or whenever passing through an enhanced tile. The next normal attack deals 160% damage to the enemy and 80% damage to enemies in 4 tiles in a cross shape around. ATK is increased by 4% in this round per use of One with the Duel, up to a maximum of 20%.

Hiiro’s equipment skills improve her damage dealing capabilities, and it syncs well with her conversion capabilities from her active. Since she can create green enhanced tiles, she’ll be able to use her equipment’s capabilities as she passes through them.

With the Duel Stance, she is able to deal higher damage, as well as extra damage to surrounding enemies. If there are enemies on her pathway of green tiles, you’ll be able to maximize your damage output. This is also helpful when you’re on a forest team with a dedicated converter.

Breakthrough Bonuses

Breakthrough 1HP increased by 300.
Breakthrough 2DEF increased by 40.
Breakthrough 3Active Skill Enhancement: Changes Active Skill to Preemptive Strike. Available upon entering combat.
Breakthrough 4Increased by 300+5% Basic max HP.
Breakthrough 5Increased by 40+5% Basic DEF.
Breakthrough 6Active Skill Enhancement: Has an increased chance to generate Green tiles when generating new tiles.

Hiiro’s offense and secondary conversion are improved once you are able to get the proper breakthrough bonuses. You will now be able to strike with your active skill at the start of the round, this lets you have more green tile options when beginning, as well as getting the enhanced versions needed for her equipment skill.

Not only that, but you’ll be able to gain more chances of creating green tiles. Not only do you get a detonator, but you’ll have a semi-converter which provides you with a lot more flexibility. She will be able to provide you with a lot of benefits especially on instances such as the Spire.
