# Otto Suwen Otto Suwen has the practiced alertness of someone who would rather read a situation than be surprised by it. Watching him, I enjoy the little calculations that seem to pass across his face before he commits to a line or a choice. He brings a useful friction to Re:Zero: big emotions are never far away, yet Otto makes room for doubt, irritation, and the plain need to keep going. That grounded quality gives his scenes a different pulse from the series' more theatrical intensity. ## Fast Facts - **Japanese name:** オットー・スーウェン - **Age:** 20 - **Birthday:** March 24 - **Height:** 177 cm - **Weight:** 60 kg - **Species:** Human - **Gender:** Male - **Affiliation:** Kingdom of Lugunica, Emilia Camp - **Japanese VA:** Kouhei Amasaki - **English VA:** Zach Aguilar ## Spoilers (reveals from later in the story) - **Occupation:** Internal Affairs Officer of the Emilia Camp ## Appearance At 177 cm and 60 kg, Otto has a lean silhouette that the animation can make feel quick without turning him into a spectacle. His design reads clearly in group scenes, but it is his expression that tends to hold my attention: a careful look can suggest he is weighing the cost of speaking. The show gives his reactions enough space to register. Small shifts in posture and timing matter because he often seems to be thinking while everyone else is already moving. His presence feels human in the most useful sense: recognizable, a little exposed, and not polished into an ideal. ## Personality Otto's caution has texture. It can look like self-interest at first, and sometimes it is, but the performance leaves room for conscience to complicate the calculation. He notices pressure and responds to it with a practical streak that makes his choices feel earned. The pleasure is in watching that practicality get tested without magically disappearing. He can be funny because he is recognizably exasperated, not because the show turns him into a punchline. Kouhei Amasaki gives his voice a brisk, conversational edge, while Zach Aguilar makes the English performance equally readable. Neither version needs to announce every thought for you to follow the strain underneath. ## Otto Suwen's Story ### Spoiler-free introduction Early on, Otto is easiest to read as a person trying to stay ahead of trouble. He measures what is happening around him, and his reactions carry the appeal of someone who has not mistaken confidence for safety. Pay attention to the way he speaks when a scene becomes tense: his words can sound practical even as his attention gives away that he is not detached. That combination makes him a welcome counterweight to the series' heightened mood. He does not need to dominate a scene to change its rhythm. The early material lets viewers decide how much of his caution comes from temperament and how much from experience, and that uncertainty is part of the fun. ### Spoilers beyond the early story As the story gives Otto more weight, the gap between his sensible instincts and what he is willing to risk becomes harder to ignore. The Emilia Camp context sharpens that change: belonging can mean accepting demands that a purely self-protective person would refuse. His growth does not erase the anxious, practical voice that made him distinctive in the first place. Instead, later scenes let that voice argue with commitment, so courage feels like a choice made under pressure rather than a new personality pasted over the old one. I find that progression satisfying because the series allows him to remain ordinary in his fears while asking him to act with unusual resolve. ## Watch Otto Suwen's Story Start with Re:Zero (2016), then let the story build in order. Otto's appeal depends on seeing how his reactions gain meaning as the surrounding pressure changes, so a scattered sampler can make him seem simpler than he is. Re:Zero Season 2 is the stretch where he receives a larger share of the emotional focus, and the follow-up material gives that change room to resonate. Re:Zero (2016) is available on Crunchyroll, Hulu, and Netflix. Re:Zero Season 2, Re:Zero: Starting Life in Another World Season 2 Part 2, and Re:Zero Season 3 are available on Crunchyroll and Netflix. Re:Zero Season 4 is available on Crunchyroll. The Japanese track features Kouhei Amasaki; Zach Aguilar voices Otto in English. I would choose the language you prefer and stay with it, since his character work depends on conversational timing as much as on dramatic emphasis. **Start here:** [Re:Zero](https://hozuna.com/anime/re-zero) — Crunchyroll, Hulu, Netflix - [Re:Zero Season 2](https://hozuna.com/anime/re-zero-season-2) (2020) — Crunchyroll, Netflix - [Re:Zero: Starting Life in Another World Season 2 Part 2](https://hozuna.com/anime/re-zero-starting-life-in-another-world-season-2-part-2) (2021) — Crunchyroll, Netflix - [Re:Zero](https://hozuna.com/anime/re-zero) (2016) — Crunchyroll, Hulu, Netflix - [Re:Zero Season 3](https://hozuna.com/anime/re-zero-season-3) (2024) — Crunchyroll, Netflix - [Re:Zero Season 4](https://hozuna.com/anime/re-zero-season-4) (2026) — Crunchyroll ## Questions **How tall is Otto Suwen?** Otto Suwen is 177 cm tall and weighs 60 kg.
