Operator Overview
“You don't even recognize me on the battlefield? I just start cutting through enemies one by one with a blank expression on my face? Wow! Sounds hella badass! Wish I could watch myself out there.”
Off the battlefield, Matoimaru is a hyper-cheerful ball of energy who indulges in sparring matches, soccer games, and flower arrangements (on display every Saturday at 3pm!). On the battlefield, she is a stone-cold 4* Duelist Guard designed for single-target assassination.
Matoimaru is a rather lopsided Operator who has put all of her stats into HP and ATK, completely neglecting DEF. Her E2 Talent, Demonic Physique, passively increases her HP and lowers her DEF, and both of her Skills play into this dichotomy further. Her Skill 1, Regeneration β, is a simple self-heal that gives Matoimaru incredible self-sustain. When you need her to cut loose and kill everything, use her Skill 2, Demonic Power, which offers a crazy ATK boost in exchange for lowering her DEF to 0 for the Skill duration.
Dropping to 0 DEF can be an issue for an Operator like Matoimaru. With Demonic Power active, engaging the wrong opponent or being in range of one extra ranged unit can swiftly lead to her death. However, if you don’t overextend her, Matoimaru’s deep HP pool can absorb quite a few hits. And of course, her lack of DEF is no problem at all when it comes to killing enemy Casters. In fact, her huge HP pool and quick-charging Skills make it easy for her to tank a few magic bolts while she’s cutting a key enemy Caster to ribbons.
Newbie Tier List Explanation
Mato can satisfy your early game Duelist needs while also gaining a great Trading Post buff at E1. Overall, this makes her a more efficient development choice than Melantha, or even Skadi, since she can satisfy early-mid game combat requirements.
Skill Discussion

Note: This unit does not have Mastery grades. This means the unit is generally not one worth spending the resources of Mastery on. However this write-up should help with skill selection, should you want to use the unit regardless.
Matoimaru's massive HP pool is one of the best in the game, which is quite impressive for a 4★. She is still quite a bit off-meta, but that at least gives her some valid and useful niches, should you want to raise her up anyway. In such a case, both of her skills are potential Mastery targets. Both have differing niches and very strong gains. Her S1 is a strong self sustain skill which directly contributes to her HP tanking abilities, while her S2 is a decent (for a 1-block 4★) DPS skill. Most players shouldn't bother raising Matoimaru, but those who do will want the full M6.
Base Skill Analysis
Mato gains her second RIIC Skill at E1.
Is it worth it? Probably. This is one of the best possible Trading Post buffs, so unless the player is already running their Trading Posts full-time with Ops buffing as much or more, then Mato is a good Promote.

Profile
This nomadic warrior from the Far East joined Rhodes Island by sheer chance.
What she lacks in strategic acumen, she makes up with a mean giant sickle swing.

Increase Trust to 50.Matoimaru is a magnificent warrior from the Far East.
She is simpleminded and prone to deception. She does catch on, but a new trick will fool her again.
Her hobbies, at which she excels, are sparring, soccer, and floral arrangement. She has been known to organize events around these subjects, though her idea of organization is typically dragging people kicking and screaming into it.

Increase Trust to 100.The Oni are still a mystery to most people. Aside from living in the Far East, there seems to be little in common among the race.
However, Matoimaru is yet even more different from other Oni: Her bloodlust makes her performance on the battlefield strikingly unique, though it seems she's not aware of this fact.

Increase Trust to 150.Many Operators think Matoimaru is crude and unrefined, but they are mistaken.
They just need to check out her floral arrangements, on display every Saturday at 3pm.
The beauty she can create is positively astonishing.

Increase Trust to 200.Matoimaru is obviously self-conscious about her flaws: She is not good at controlling her strength or at critical thinking.
She took up floral arrangement to refine herself and to show the others they don't need to fear her.
Despite this, she's remains quite gullible. At least she has learned to question the idea that she must be a great thinker in order to survive.
As far as she is concerned, her ideal companion would be someone who won't deceive or betray her, and will stay with her and guide her. How wonderful that would be...
