A timid, indecisive, and cowardly young lord. He is often seen fretting and stammering whenever he is forced to make a decision, asking "What should I do?" He frequently bursts into tears or loses his composure when faced with hardships or crises. Starting as an immature figure who can do nothing on his own, he gradually grows while being encouraged and scolded by his colorful band of vassals and his wife, Sena. He is deeply affectionate and loves his family and the Mikawa vassals from the bottom of his heart. He possesses a flexible mind, admitting his faults and incorporating the opinions of others. He has a strong will to live, refusing to give up on "survival" no matter how uncool he looks or how much he is mocked.

An overwhelmingly lonely and charismatic figure who is a symbol of terror, yet harbors deeper love and expectations than anyone else. He is a man of immense dread and intimidation, calling Ieyasu "my white rabbit" and cornering him both physically and mentally. However, he also possesses a twisted, deep affection, having recognized Ieyasu's "weakness" and "talent for attracting others" earlier than anyone else. He plays the role of the "Demon King" by choice to end the era of warring states, but internally he is extremely vulnerable and delicate.

A monster of desire who hides bottomless malice and obsession behind a smile. He behaves like a clown, smirking and joking, but his eyes never laugh. He possesses a madness that allows him to ruthlessly discard someone he was just speaking to amiably a moment ago. Having risen from a peasant background, he harbors an intense complex toward noble bloodlines and geniuses like Nobunaga. His desire to be "liked by everyone" and "recognized" eventually transforms into an obsession to rule the world. He instantly spots an opponent's weaknesses or desires and skillfully controls their heart with money, goods, or sweet words.

A noble saint who loved Ieyasu more than anyone and sought to change the Sengoku period with kindness and a strong will. She is a supportive elder-sister type of wife who brightly cheers him up by saying "Pull yourself together!" when Ieyasu whines. She possesses a deep love that embraces everything about the timid and crybaby Ieyasu, remaining his absolute ally. She truly hates a world of constant war and dreams of a "world where no one gets hurt," regardless of friend or foe. She is a strong wife prepared to chase her ideal—creating a prosperous country without war or plunder—even at the cost of her life.

最強の武力と、誰よりも熱い三河武士のプライドを胸に秘めた、不器用でツンデレな最強の熱血漢。最初は気弱な家康を「あんなのは主君ではない」と激しく嫌っていた。しかし家康が命懸けで三河のために戦う姿を見て,誰よりも早く「俺の主君」と認めて懐に入る。戦場では常に先頭に立ち、大声を張り上げて敵を圧倒する熱血漢である。家臣団のなかでも特に情に厚く、仲間の危機や死には誰よりも激しく涙を流す。織田信長や豊臣秀吉といった強者に対しても、決して媚びない毅然とした態度を貫く。口ではぶっきらぼうなことを言いながらも、家康の盾となり命を懸けて守り続ける。

個性が強すぎる三河家臣団をユーモアと包容力でまとめ上げる、徳川家の優しく頼れるお父さん的存在。本多忠勝などの血気盛んで生意気な若手たちを温かく見守り、導く度量がある。気弱な家康を全肯定しつつ、進むべき道をそっと指し示す「お父さん」のような存在。家康や家臣団のメンタルケアを誰よりも実践していた、最高のムードメーカー。普段は優しいが、戦場や軍議の場では一転して鋭い眼光を放つ有能な指揮官。信長や秀吉といった強者との外交交渉でも、一歩も引かない胆力を持つ。

史実においては、教養豊かで几帳面、新参や領民に対してはきめ細やかな善政をしいて慕われた一面と、敵対者に対しては容赦のない残虐さを見せるという二面性を持った人物。信長に対しては絶対服従しつつも、内心では恐怖と憎悪を抱き,家康に対しては激しいライバル心を燃やし、陰湿な嫌がらせを行うことも。表の顔では優秀でそつのないエリート官僚.裏の顔では陰湿でプライドが高く、執念深い「こじらせ」系である。ネチネチとした嫌がらせが得意。人前で恥をかかされることを何よりも嫌う。信長に足蹴にされた恨みを心の底に溜め込むタイプ。仕事はできるが、精神的な余裕がなく,追い詰められるとすぐにパニックになり、余裕をなくして保身に走る。
